Description

Measuring section of combustion chamber test equipment and combustion chamber test equipment

Technical Field

The invention relates to the field of cooling of combustion chamber test equipment, in particular to a measurement section of combustion chamber test equipment and the combustion chamber test equipment.

Background

At present, the development of the combustion chamber part mainly follows the modes of single-head test, multi-head fan test and full-ring test to verify and optimize the design scheme of the combustion chamber part. In the three test modes, combustion performance tests including an outlet temperature distribution test, a pollutant discharge test, a combustion efficiency test and the like are required. The performance test of the combustion chamber is different from the common flow heat exchange test, and the performance test of the combustion chamber cannot be replaced by a low-temperature low-pressure test or a medium-temperature medium-pressure test according to a similar rule, so that the performance of the combustion chamber is a high-temperature high-pressure test, and the import test parameters need to be the same as or close to the design parameters of components as much as possible.

Along with the continuous improvement of the thrust-weight ratio of the engine, the temperature rise of the combustion chamber is also continuously improved, so that in a combustion chamber test, a combustion chamber test piece body (a test section) and a rear measurement section connected with the test section are required to bear the scouring of high-temperature and high-pressure gas, and a severe cooling problem is faced; in a sector combustion chamber test, because the design difficulty of a rotary displacement mechanism is too large, a fixed sensing part is often adopted for measurement, in order to obtain as many data points as possible, the sensing parts as many as possible need to be adopted, and therefore the cooling structure design of a rear measurement section of the sector combustion chamber is inevitably more difficult. At present, the cooling structure design problem of back measurement section needs to be solved urgently, guarantees that it both can stable operation, does not influence the export measurement of combustion chamber operating condition again, still needs to guarantee simultaneously that the cost is lower.

It is noted that the information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "central," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the scope of the invention.

In one exemplary embodiment of the combustor test rig measurement section provided by the present invention, as shown in fig. 1, the measurement section includes a first tube 3, a second tube 4, and a baffle assembly, the second tube 4 being disposed within the first tube 3, and the second tube 4 having a diameter less than the diameter of the first tube 3, an annular space being formed between an inner wall of the first tube 3 and an outer wall of the second tube 4, the baffle assembly being configured to divide the annular space into at least two cooling zones independent of each other, the cooling zones being configured to cool the first tube 3 and the second tube 4 and other components disposed adjacent to the first tube 3 and the second tube 4.

As shown in fig. 3 and 4, the inner space of the second pipe 4 is used for flowing the high-temperature and high-pressure fuel gas 100.

In the above exemplary embodiment, the annular space formed between the first tube 3 and the second tube 4 is divided into at least two cooling areas independent of each other by the partition plate assembly, so that the cooling medium can be independently configured for each cooling area, different types of cooling media can be adopted in different cooling areas according to actual needs to meet different cooling requirements, the flow area of the cooling medium input into each cooling area can be reduced, the problems of uneven cooling effect, easy occurrence of flow dead zones and the like caused by insufficient pressure and the like when the cooling medium needs to flow in the whole annular space are avoided, and the cooling effect is improved.

Further, the measuring section of the combustor test equipment further comprises a first end piece 1, a second end piece 2, a first end piece cooling channel 101 and a second end piece cooling channel 201, wherein the first end piece 1 is connected to the first ends of the first pipe 3 and the second pipe 4, the second end piece 2 is connected to the second ends of the first pipe 3 and the second pipe 4, the first end piece cooling channel 101 is used for cooling the first end piece 1, and the second end piece cooling channel 201 is used for cooling the second end piece 2.

Wherein the combustor test equipment measurement section is configured such that the cooling medium enters the first end piece cooling passage 101, then enters the second end piece cooling passage 201 through one of the cooling passages 400 of the cooling zone, and finally enters the other cooling passages 400 of the cooling zone.

As shown in fig. 5 and 6, a plurality of cooling channels 400 are provided in the cooling area, and for each cooling area, a section of the first end part cooling channel 101 and a section of the second end part cooling channel 201 correspond to the cooling area, so that when circulating, a cooling medium firstly enters the first end part cooling channel 101 to cool the first end part 1, then flows out of the first end part cooling channel 101, enters the second end part cooling channel 201 through one of the cooling channels 400 in the cooling area, cools the second end part 2, and finally flows out of the second end part cooling channel 201, and enters the other cooling channels 400 in the cooling area to cool the cooling area.

The advantage of setting up like this is, can increase the time that cooling medium stayed in first end piece cooling channel 101 and second end piece cooling channel 201 to make cooling medium can flow through all positions of first end piece cooling channel 101 and second end piece cooling channel 201 as far as possible, in order to carry out more fully cooling to first end piece 1 and second end piece 2, the cooling effect is better, effectively improves the life of first end piece 1 and second end piece 2, makes its non-deformable, avoids causing the leakage risk. If the cooling medium enters the first end piece cooling channel 101, then enters the cooling region, and finally enters the second end piece cooling channel 201 after flowing through the entire cooling region, the cooling medium may not flow through the entire space of the first end piece cooling channel 101 and then directly enter the cooling region under the impact action, or may not flow through the entire space of the second end piece cooling channel 201 due to insufficient power after passing through the cooling region, and the like, thereby failing to sufficiently cool the first end piece 1 and the second end piece 2.

Optionally, the at least two cooling zones are arranged circumferentially of the annular space. This arrangement further facilitates the arrangement of the cooling passage 400 and also facilitates the flow of the cooling medium.

Optionally, the diaphragm assembly includes a first diaphragm 401 and a second diaphragm 402, the first diaphragm 401 and the second diaphragm 402 are both arranged in a radial direction of the annular space and are respectively located at different positions in a circumferential direction of the annular space, and at least two cooling areas are formed by the first diaphragm 401 and the second diaphragm 402.

The number of the first partition 401 and the second partition 402 can be flexibly selected according to actual needs to form different numbers of cooling areas. The following description will be given taking as an example that the first separator 401 and the second separator 402 are each provided with one and form two cooling regions.

Referring to fig. 1, 2, 7 and 8, the second tube 4 is provided with a plurality of holes, specifically including two first holes 415 and five second holes 416, where the five second holes 416 are closer to each other, the two first holes 415 are respectively disposed at two sides of the five second holes 416, and a distance between the two first holes 415 and the nearest second hole 416 is greater than a distance between two adjacent second holes 416. These holes are used for mounting the sensed part mounting seat, specifically, the first hole 415 is used for mounting the first sensed part mounting seat 5, and the second hole 416 is used for mounting the second sensed part mounting seat 6, wherein the five second holes 416 are closer to each other, so that after the second sensed part mounting seat 6 is mounted, the five second sensed part mounting seats 6 can be integrally connected with each other, which can make the structure more compact, avoid the space waste caused by mounting the sensed part mounting seats separately, and also can arrange the sensed parts (i.e. the measuring points) as much as possible. And the other two first sensitive part mounting seats 5 are arranged relatively independently, so that the effectiveness of test measurement can be improved.

When not in use, the sensitive part mounting base can be sealed by the mounting plate 7 and the bolt 10.

In order to achieve a better cooling effect, optionally, a cooling channel may be opened between the two sensitive part mounting seats.

Specifically, as shown in fig. 7 and 8, the first diaphragm 401 is provided on one of the second sensitive portion mounting seats 6, and thus the first diaphragm 401 includes two stages, with the middle being partitioned by the second hole 416. As shown in fig. 9, the second partition 402 includes an integral segment arranged in a radial direction.

Optionally, a first baffle 401 is located in the upper portion of the annular space and a second baffle 402 is located in the lower portion of the annular space, such that each cooling zone includes an upper partial annular space and a lower partial annular space. The arrangement is more convenient for the flow of the cooling medium, and is beneficial to enabling the cooling medium to flow through all the spaces of the cooling area as far as possible, and avoiding the flowing dead zone.

One of the cooling zones (a) will be described as an example.

Optionally, the radial edge of the cooling zone close to the first end piece 1 is provided with a third partition 403 extending in the circumferential direction, the side of the first end piece 1 close to the first tubes 3 is provided with a first groove opening towards the first tubes 3, the third partition 403 is used for forming the first end piece cooling channel 101 with the first groove and for at least partially isolating the first end piece cooling channel 101 from the cooling zone, corresponding to the first end piece cooling channel 101 being formed opposite the cooling zone by the third partition 403 and the first groove. The arrangement can ensure that the cooling medium can flow through all the spaces of the first end piece cooling channel 101 and then flow out as much as possible after entering the first end piece cooling channel 101, so that the first end piece 1 can be cooled sufficiently, and the cooling effect on the first end piece 1 is improved.

Further, as shown in fig. 11, a fifth partition 405 and a sixth partition 406 are provided in the first groove, the fifth partition 405 and the sixth partition 406 are also arranged in the radial direction of the first tube 3 and the second tube 4, the fifth partition 405 is connected to the first partition 401, and the sixth partition 406 is connected to the second partition 402, so that both ends of the first end member cooling passage 101 are closed by the fifth partition 405 and the sixth partition 406. This forms a relatively independent first end member cooling passage 101.

Optionally, the fifth and

sixth baffles

405, 406 are rounded at the junction to reduce flow losses. Optionally, the radius is one third to one half of the radial thickness of the annular space between the first tube 3 and the second tube 4.

Further, a first opening 421 is provided between the first end of the third separator 403 and the first separator 401, a second opening 422 is provided between the second end of the third separator 403 and the second separator 402, and the first opening 421 and the second opening 422 are used to communicate the cooling area with the first end part cooling passage 101, so that the cooling medium entering the first end part cooling passage 101 from the second opening 422 flows through the first end part cooling passage 101 and then enters one of the cooling passages 400 in the cooling area from the first opening 421.

As shown in fig. 8, a third baffle 410 may be provided at the first opening 421 for dividing the flow of the cooling medium into at least two flows so that the cooling medium can flow through the entire area at the first opening 421 as much as possible. The third baffle 410 may have a straight-line segment structure as viewed from above. As shown in fig. 9, a second baffle 412 is disposed at the second opening 422, as will be described in detail below.

Similarly, the radial edge of the cooling zone close to the second end piece 2 is provided with a circumferentially extending fourth partition 404, the side of the second end piece 2 close to the first tube 3 is provided with a second groove opening towards the first tube 3, the fourth partition 404 being intended to form the second end piece cooling channel 201 with the second groove and to at least partly isolate the second end piece cooling channel 201 from the cooling zone. The arrangement can ensure that the cooling medium can flow through all the spaces of the second end piece cooling channel 201 as much as possible and then flow out after entering the second end piece cooling channel 201, so that the second end piece 2 can be cooled sufficiently, and the cooling effect on the second end piece 2 is improved.

Further, a seventh partition 407 and an eighth partition 408 are provided in the second pocket, the seventh partition 407 is connected to the first partition 401, and the eighth partition 408 is connected to the second partition 402, so that both ends of the second end member cooling passage 201 are closed by the seventh partition 407 and the eighth partition 408. This forms a relatively independent second end member cooling passage 201.

Optionally, the seventh and

eighth partitions

407, 408 are rounded at the junction to reduce flow losses. Optionally, the radius is one third to one half of the radial thickness of the annular space between the first tube 3 and the second tube 4.

Further, a third opening 423 is provided between the first end portion of the fourth separator 404 and the first separator 401, a fourth opening 424 is provided between the second end portion of the fourth separator 404 and the second separator 402, and the third opening 423 and the fourth opening 424 are used for communicating the cooling region with the second end part cooling passage 201, so that the cooling medium entering the second end part cooling passage 201 from one of the cooling passages 400 in the cooling region through the third opening 423 flows out from the fourth opening 424 after flowing through the second end part cooling passage 201, and the cooling medium flowing out from the fourth opening 424 enters the other cooling passages 400 in the cooling region.

As shown in fig. 8, a third baffle 410 may be provided at the third opening 423 for dividing the flow of the cooling medium into at least two flows so that the cooling medium can flow through the entire area at the third opening 423 as much as possible. As shown in fig. 9, the fourth baffle 414 is provided at the fourth opening 424, and the fourth baffle 414 may have a linear section in plan view.

Optionally, the cooling zone is provided with S-shaped cooling channels. The S-shaped cooling channels have the advantages that the flow directions of the two adjacent transverse cooling channels can be opposite, the amount of the cooling medium in each cooling channel is better ensured, and the cooling effect is improved.

Specifically, a plurality of ninth partition plates 409 are provided in the cooling area, one of the adjacent two ninth partition plates 409 is connected to the third partition plate 403 and provided with a fifth opening 425 between the fourth partition plate 404, and the other of the adjacent two ninth partition plates 409 is connected to the fourth partition plate 404 and provided with a sixth opening 426 between the third partition plate 403 and the fourth partition plate 404, so that an S-shaped cooling passage is formed in the cooling area by the third partition plate 403, the ninth partition plates 409 and the fourth partition plate 404.

Optionally, a plurality of sensing portions are disposed on the first tube 3, and at least one sensing portion is disposed on the ninth partition 409. The ninth partition 409 provided with the sensitive part includes two sections, and the ninth partition 409 not provided with the sensitive part includes a continuous whole section.

Optionally, a first baffle 411 is provided at the fifth opening 425 and/or the sixth opening 426, the first baffle 411 being adapted to divide the flow of the cooling medium flowing through the fifth opening 425 and/or the sixth opening 426 into at least two flows. This has the advantage that the cooling medium can be made to flow through the entire area of the fifth openings 425 and/or the sixth openings 426 as far as possible, rather than only laterally adjacent to the ninth baffle 409 or to the third baffle 403 or the fourth baffle 404, which can achieve a more complete cooling effect and prevent dead flow zones.

Optionally, the first baffle 411 is C-shaped, an opening of the first baffle 411 faces the ninth baffle 409, the first baffle 411 is not in contact with the ninth baffle 409 or the third baffle 403 or the fourth baffle 404, a first preset distance is provided between the first baffle 411 and the ninth baffle 409, and a second preset distance is provided between the first baffle 411 and the third baffle 403 or the fourth baffle 404. Alternatively, both extending ends of the first baffle 411 are straight line segments, so that the flow of the cooling medium can be better guided.

Optionally, the combustor test equipment measurement section further comprises at least two inlets and at least two outlets communicating with the at least two cooling zones, respectively, the inlets being arranged below the second tube 4 and the outlets being arranged above the second tube 4. This arrangement is advantageous in that the cooling medium flows through more positions in the cooling region, improving the cooling effect.

Alternatively, the inlet is arranged close to the first end piece 1 and the outlet is arranged close to the second end piece 2. Thus, the cooling medium can enter the first end piece cooling channel 101 and flow out of the second end piece cooling channel 201 more conveniently; but also can provide enough installation space for the liquid inlet pipe connected with the inlet and the liquid outlet pipe connected with the outlet, and the operation is convenient.

As shown in fig. 10, in order to form the relatively closed and independent first and second

header cooling passages

101 and 201, the end of the first tube 3 is provided with a first tube extension 31, and the end of the second tube 4 is provided with a second tube extension 41 to be butted against the third and

fourth partitions

403 and 404, respectively, to form the first and second

header cooling passages

101 and 201, preventing the cooling medium from leaking.

As shown in fig. 7, 8 and 10, the outlet is provided between the third partition 403 and the fourth partition 404 at a position close to the fourth partition 404, and the ninth partition 409 closest to the outlet has an opening between the third partition 403 and the fourth partition 404.

Generally, the ninth baffle 409 closest to the outlet is connected to the fourth baffle 404 so that the cooling medium flows from the side away from the outlet to the outlet by the ninth baffle 409, and thus there will be an opening between the ninth baffle 409 and the third baffle 403. However, in order to prevent the flow dead zone from being formed in the region between the outlet and the fourth partition 404, an opening is also formed between the ninth partition 409 and the fourth partition 404, so that a part of the cooling medium can flow to the region between the outlet and the fourth partition 404 through the opening and then flow out through the outlet, thereby avoiding the flow dead zone and achieving a more comprehensive cooling effect.

Optionally, the flow rate of the opening between the ninth partition 409 and the fourth partition 404 is smaller than the flow rate of the opening between the ninth partition 409 and the third partition 403. This has the advantage of ensuring that both the majority of the cooling medium still flows along the ninth partition 409 from the side remote from the outlet to the outlet and that a portion of the cooling medium can flow to the region between the outlet and the fourth partition 404.

Alternatively, the width of the opening between the ninth barrier 409 and the fourth barrier 404 closest to the outlet in the radial direction may be 2 to 5 mm.

As shown in fig. 9, an inlet is provided between the third partition 403 and the fourth partition 404 at a position near the third partition 403, a second baffle 412 is provided at the inlet (or at the second opening 422), and the second baffle 412 is used for dividing the flow of the cooling medium flowing out of the inlet into at least two flows. This has the advantage that the cooling medium can be made to flow through the entire area at the inlet as much as possible, rather than against the sides only at a position close to the third partition 403 or close to the second partition 402, which can achieve a more comprehensive cooling effect and prevent dead zones from occurring.

Optionally, a tenth partition 413 disposed to intersect with the second partition 402 is further provided at the inlet, the inlet is disposed in an area adjacent to the third partition 403 among four areas formed by the intersection of the second partition 402 and the tenth partition 413, and the ninth partition 409 may be normally disposed in an area adjacent to the fourth partition 404. By providing the tenth partition 413, the cooling medium flowing out through the inlet can be made to flow toward the first-end-piece cooling passage 101 more smoothly.

Alternatively, the second baffle 412 includes an arc-shaped section and a straight section, one end of the arc-shaped section is connected to the liquid inlet pipe disposed at the inlet, and the other end of the arc-shaped section is connected to the straight section, and the straight section extends toward the first end member cooling passage 101. The arc-shaped section can reduce flow loss, simultaneously ensure that a cooling medium flow smoothly flows to the first end piece cooling channel 101, ensure the uniformity of flow and fully cool the heated surface of the first end piece 1; the straight line section can form a fluid impact effect, and the cooling effect is better.
