Technical field
The utility model relates to a kind of pressurize delivery device, especially a kind of pressurize delivery device for PIV experiment trace particle.
Background technology
PIV(particle image velocimetry) technology is the novel flow measurement of one and the display technique growing up the eighties in 20th century, in the situation that stream field does not produce interference, the flow situation of stream field is observed.The principle of its work is to add trace particle in need observation flow field, and follow the tracks of flow field and move, CCD(charge coupled cell) this particle of cameras record certain moment in flow field optical imagery and be transferred to data acquisition system (DAS), then particle picture is carried out analyzing and processing and just can be obtained the flow field kinematic parameter in this moment, and in PIV experiment actual measurement be the motion morphology of trace particle.Main by the processing to a large amount of particle pictures, thus the parameters of this Field Characteristics of reflection such as speed, vorticity, streamline, line of equal velocity of this flow observation face obtained, obtain thus motion state and real phenomenon that trace particle reflects fluid.
The concentration situation that a key factor of PIV experiment success is particle, especially for wind tunnel experiment at a high speed, the selection of trace particle and dispense and affect directly or indirectly particle concentration.Wherein, the dispense technology of trace particle in flow field is extremely important link in PIV experiment.The riding quality of trace particle in flow field, directly affects true, accurate, the degree of reliability that PIV describes tested flow field objective reality.And the riding quality of trace particle in flow field greatly relies on the mode that trace particle dispenses.To same tested flow field, owing to taking different trace particles to dispense mode, PIV experiment may be measured accuracy, precision all the result of suitable difference, and the careful degree of thus tested flow field being described is not identical yet.
At present, in PIV experiment, there are two kinds of conventional trace particle modes that dispense:
First kind of way is: by the pipeline of tested model inside, evenly dispense trace particle at some position of model to tested region.This kind of mode has use in Complex Flows measurement and boundary layer measurement.
The second way is: in whole flow field, evenly dispense trace particle, or in local flow field, evenly dispense trace particle.This is the current PIV the most frequently used mode that tests the speed.This kind of mode can evenly dispense trace particle to regional area or the whole flow field of test section by the stable section of wind-tunnel.But be placed in stable section owing to dispensing pipeline, distance test (DT) section is nearer, inevitably there is to certain influence in test section flow field.Need to take some measures, reduce and dispense the impact of pipeline on test section flow field.In return circuit wind tunnel, can evenly dispense trace particle to whole flow field by the diffuser of wind-tunnel.It dispenses pipeline and is placed in diffuser, can not produce any impact to test section flow field, forms the trace particle stream of higher quality, follows to stable and uniform air-flow and is covered with whole test section, flows through tested region, but the local flow field of CCD camera is taken and made some difference.
Above-mentioned two kinds of modes are mainly the operations while throwing in trace particle in testing for low-speed wind tunnel, and carry out high-speed wind tunnel experiment once needs, high velocity air can cause trace particle in tested flow field to be blown and fly at short notice after entering tested flow field, thereby cannot make the airflow field that exists all the time trace particle to mix in tested flow field, affect largely accuracy and the precision of PIV experiment.In addition, in PIV experimentation, the equipment such as CCD camera can not move easily, otherwise have a strong impact on experimental result after laying, and the input of traditional trace particle is larger by equipment volume, are unfavorable for system with use.Therefore, how rationally to dispense trace particle, the flow field figure that obtains high-quality looks like to be called the key of PIV experiment.
