Description
Technical field
The present invention relates to the high temperature difference big flow mixing arrangement in aerospace field, more particularly to low-temperature working part,
Specifically related to a kind of low flow resistance eddy flow diffusion air and liquid mixer.
Background technology
Blender is widely used in the every field of daily life, research and production, such as petrochemical industry, Aero-Space and all kinds of
Testing equipment, to strengthen the industrial operation processes such as mixing, heat transfer, absorption and heterogeneous reaction.The operation principle of blender be according to
Mixed cell effect by being assembled in inside, makes two kinds of fluids mutually blend, exchange heat when blender flows inside, is going out the degree of lip-rounding
Into temperature unification, the uniform medium of speed.By taking space product as an example, rocket engine as rocket system core component, its
The high reliability of work is set up on the high stability basis supplied in fuel.Using internal in-line arrangement fin more than existing blender
Kind of the fluid of structure, i.e., two produces disturbance when being flowed around fin, occurs the complicated motions such as shunting, interflow, rotation, promotes two kinds
Fluid all reaches good disperse.Because fin is in-line arrangement mode, two kinds of fluid turbulent degree are low, mix, exchange heat insufficient, outlet
Speed, temperature uniformity it is difficult to ensure that, be unfavorable for the homogeneous supply of fuel stabilization.
The content of the invention
The technical problem to be solved in the present invention is：Improve the deficiency of existing structure, solve mixer outlet gas temperature, speed
The problem of spending uneven strengthens mixed effect there is provided a kind of low flow resistance eddy flow diffusion air and liquid mixer from structure design, it is ensured that
Fuel supply is more reliable and more stable.
Realize the technical scheme of the object of the invention：A kind of low flow resistance eddy flow diffusion air and liquid mixer, the mixer case one
Hold as liquid inlet, the other end is outlet；Pipe cyclone is set inside liquid inlet, and the end of pipe cyclone connects porous diffusion
Device, the other end of porous air diffuser connects porous curved baffle；Gas is opened up on the mixer case at porous air diffuser position
Body entrance；Three groups of wrong platoon leader's fin mixed cells are set at mixer case bosom, and every group of wrong platoon leader's fin mixing is single
Member is made up of orthogonal two pieces of semi-circular fins, and the fin direction of rotation phase of adjacent two wrong platoon leader's fin mixed cells
Instead；Liquid enters from liquid inlet during work, flows through and is divided into two after pipe cyclone, and flows into porous air diffuser, gas to rotate
Enter from gas access, flow through porous curved baffle, liquid with being flowed out in porous air diffuser is diffused mixed after gas slows down
Close, three groups of wrong row's fin mixed cells are sequentially entered through preliminary mixed gas-liquid, gas-liquid is forced eddy flow and is divided into two strands
Fluid, and gas-liquid occurs flow direction twice and changes, and turbulent closure scheme ultimately forms the uniform mixture of temperature, composition from going out
Mouth outflow.
Open up some on a kind of low flow resistance eddy flow diffusion air and liquid mixer as described above, the porous curved baffle described in it
Arrange aperture.
The remarkable result of the present invention is：Low flow resistance eddy flow diffusion air and liquid mixer of the present invention, adds entrance
Pipe cyclone, is changed into eddy flow mixing from single diffusion mixing, improves two kinds of fluid turbulent degree, enhance mixed effect；Increase
Porous air diffuser and arcuated porous baffle plate, improve diffusion velocity, extend incorporation time；Have changed fin arrangement mode and
Length, adds irregular disturbance, causes bigger turbulence intensity.Meanwhile, estimated through numerical simulation and verification experimental verification, outlet pressure
Power descends below 3% compared with inlet pressure.So referred to as low flow resistance eddy flow diffusion air and liquid mixer.The low flow resistance eddy flow of the present invention expands
Dissipate air and liquid mixer before thrust chamber head, heat exchange for two-way fuel, mixing, formed temperature it is homogeneous,
Speed stable air-flow, is burnt into thrust chamber.Examine and verify by multiple heat examination, technical feasibility, mixer outlet temperature
The degree uniformity is significantly improved, by adjusting two-way fluid flow, outlet temperature can be achieved adjustable (± 60 DEG C).

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is made to a kind of low flow resistance eddy flow diffusion air and liquid mixer of the present invention
It is further described.
As shown in figure 1, a kind of low flow resistance eddy flow diffusion air and liquid mixer of the present invention, the mixer case one end is
Liquid inlet 1, the other end is outlet 7；Pipe cyclone 2 is set inside liquid inlet 1, and the end of pipe cyclone 2 connects porous diffusion
Device 3, the other end of porous air diffuser 3 connects porous curved baffle 5；Opened on the mixer case at the position of porous air diffuser 3
If gas access 4；
Three groups of wrong platoon leader's fin mixed cells 6, every group of wrong platoon leader's fin mixing are set at mixer case bosom
Unit 6 is made up of orthogonal two pieces of semi-circular fins, and the fin rotation side of adjacent two wrong platoon leader's fin mixed cells 6
To on the contrary, add mixing intensity, mixing uniformity is improved.
Liquid enters from liquid inlet 1 during work, is divided into two after flowing through pipe cyclone 2, produces radial rotary speed, plays rotation
Two strands of liquid afterwards accelerate diffusion by the aperture on porous air diffuser 3；Gas enters from gas access 4, flows through porous arc
Baffle plate 5, gas is diffused with the liquid flowed out in porous air diffuser 3 after slowing down and mixed, through preliminary mixed gas-liquid successively
Into three groups of wrong row's fin mixed cells 6, gas-liquid is forced eddy flow and is divided into two fluids, and gas-liquid occurs to flow twice
Direction changes, turbulent closure scheme, ultimately forms the uniform mixture of temperature, composition and is flowed out from outlet 7.
As shown in Fig. 2 opening up some row's apertures on described porous curved baffle 5.Described porous curved baffle, reduction
Gas flow rate, extends the gas-liquid mixed time and reaches current balance function.
Low flow resistance eddy flow diffusion air and liquid mixer of the present invention, solves asking for mixer outlet lack of uniformity
Topic.First, in the original liquid-inlet increase pipe cyclone 2 of blender, liquid in rotation is caused by the effect of pipe cyclone 2, footpath is produced
To speed；Porous air diffuser 3 is set in the downstream of pipe cyclone 2 so that liquid is further increased by radial flow speed during aperture, reinforcing
Diffusion is mixed between liquid and gas；Porous curved baffle is set in gas access downstream, to disturb gas, gas stream is reduced
Speed, extends the gas-liquid mixed time, optimization blending；Existing in-line arrangement short wing panels are changed to wrong platoon leader's fin, above carried from structure design
High fluid turbulent degree.By eddy flow, diffusion, realize that two kinds of fluids are quick, uniformly mix.
