Description
Technical field
The present invention relates to a kind of proving installation in hydrodynamic calculations field, or rather, the present invention relates to a kind of integrated planar induced with laser screen light technology (Planar laser-induces fluorescence, be called for short PLIF) and the fluid power turbomachine flow field three-dimensional comprehensive proving installation of Particle Image Velocimetry (Part icle Image Velocimetry, abbreviation PIV).
Background technology
Fluid power turbomachine flow field is complicated three-dimensional flow, as fluid torque-converter, Retarder, fluid coupling etc., because cube theory is still immature, can not be used for carrying out accurate computation and analysis to the flow field of fluid power turbomachine.At present, mainly pass through Fluid Mechanics Computation (Computational Fluid Dynamics is called for short CFD) numerical simulation for the research of fluid power turbomachine performance both at home and abroad, flow field is studied.But the flow field analysis using CFD to carry out at present is carried out under many simplified conditions, the Steady state hypothesis done only reflects the statics characteristic of element, the model of numerical simulation is complete not enough, CFD analyzes the numerical simulation still belonging to authenticate forward character, could not ripe be applied in the parameter optimization of hydrodynamic unit.Therefore, directly have great importance for the analysis of experiments of three-dimensional flow field.
Two classes are mainly divided into the analysis of experiments device of fluid power turbomachine flow field: contact type measurement and non-contact measurement.Enter 21 century, the development of non-contact measuring technology, make the flow field experimental test of fluid power turbomachine obtain develop rapidly.Main flow is become by the non-contact measurement turbomachine interior flow field of optics, as laser Doppler test instrument (Laser Doppler Anemometry, be called for short LDA), Particle Image Velocimetry (Particle Image Velocimetry, be called for short PIV).
Laser Doppler Velocimeter (LDA) is a kind of measuring technique of contactless direct measurement flow field spot speed.Namely the laser of a branch of frequency stabilization is irradiated on moving target, and due to Doppler effect, the backward astigmatism of target will produce certain frequency displacement, by obtaining the velocity information of moving target along beam direction to the measurement of rear orientation light Doppler shift.Measuring accuracy due to Laser Doppler Velocimeter and the non-invasive measurement to flow field, so be applied in the velocity survey of fluid power turbomachine flow field.But because LDA technology can only measure flow field single-point speed, and can not obtain whole flow field velocity distribution, therefore directly can not do flow analysis to flow field whole flow field, this just constrains the deep application that LDA technology is tested at flow field.
Particle Image Velocimetry (PIV) is a kind of contactless indirect inspection flow field velocity field measuring technology.In test process, selection has good flow followability and light scattering trace particle is sowed in flow field, then use laser light sheet a certain test flat illumination in tested flow field, by image capturing system (as CCD camera etc.), record the flow field particle picture in t1, t2 moment respectively, through Digital Image Processing, try to achieve the displacement of particle in twice shooting time interval, can velocity field be calculated.Because PIV technology stream field is noiseless, and the instantaneous velocity field of flow field can be obtained, carry out whole audience quantitative measurment, therefore significant to the research of the fine structure flowed and mechanism thereof, be the technology of a kind of advanced person measuring complex flowfield.But because the VELOCITY EXTRACTION problem between two two field pictures causes the measuring accuracy of PIV and counting yield still to have much room for improvement.At present, although Many researchers has proposed many methods to improve VELOCITY EXTRACTION algorithm, as topology graph theory, neural network, genetic algorithm, fuzzy clustering scheduling algorithm, but the improvement of this algorithm is all based on numerical imaging algorithm itself, from flow field, do not obtain more synchronizing informations to improve accuracy and the validity of VELOCITY EXTRACTION by other devices, so improve limited to the Accuracy and high efficiency of the VELOCITY EXTRACTION of PIV technology.
PLIF full name is planar laser induced screen light technology (Planar Laser Induces Fluorescence, be called for short PLIF), namely the sheet light source irradiation measurand of characteristic frequency is applied, measurand generation resonant transition becomes excited state, the measurand being positioned at excited state to send by the sheet light source of this characteristic frequency excite the fluorescence signal of induction, then adopt receiving device to accept fluorescence signal, this detection test technology is just called PLIF technology.PLIF technology has obtained deeply applying widely in combustion diagnosis, measurement of concetration, and it also to be succeeded utilizations in fluid mechanics test fields of measurement simultaneously, can to the temperature in flow field, and pressure does the analysis of quantitative and qualitative analysis, studies application prospect very wide.But the case directly PLIF technology be applied in the test of fluid power turbomachine flow field is few in the world, because the fluorescence intensity that PLIF technology obtains just directly has functional relation with tested fluorescent material concentration, the distribution of concentration of measured matter namely can be measured; Compare by two and also can obtain the funtcional relationship of fluorescence intensity and fluorescent material temperature, namely also can measure the thermo parameters method of measured object.The key that fluid power turbomachine flow field is measured is exactly the measurement of speed, temperature, pressure.
Therefore, the device that turbomachine flow field obtains whole audience velocity field visual image and flow field temperature, pressure information can be measured more accurately and efficiently in the urgent need to a kind of, carry out the complex three-dimensional flow field motion that system comprehensively analyzes fluid power turbomachine, optimize the design of impeller blade.
