Description
Technical field
The invention belongs to fluid velocity field measurement field, more particularly to a kind of tracer grain for Two-Phase Flow Field PIV measurements
Sub- sowing apparatus and operating method.
Background technology
At present, the method for measuring liquid flow field has：(1) pibtot's tub velocimetry；(2) hot line/hotting mask velocimetry；(3) LDV swashs
Light Doppler and correlation technique；(4) PIV technologies.
LDV is Doppler signal of the measurement by the trace particle of laser probe, further according to speed with
The relation of Doppler frequency obtains speed.Due to being laser measurement, not interfered with for flow field, the scope that tests the speed is wide, and due to
Doppler frequency and speed are linear relationships, and the temperature of the point, and pressure is not related, are current tachometric survey precision in the world
Highest instrument.Functionally it is divided into：Light path part, signal processing.Light path part：Using He-Ni lasers or Ar from
Sub- laser, it is because they can provide high-power 514.5nm, the laser of tri- kinds of wavelength of 488nm, 476.5nm.A new generation
LDA systems use solid state laser, significantly reduce to operator use experience requirement.Optical splitter with frequency shifting arrangement
Laser is divided into equicohesive two beam, by single-mode polarization maintaining fiber and fiber coupler, laser is sent to laser emission probe, is adjusted
Whole laser focuses on same point in waist part, and to ensure minimum measurement volume, this point is exactly to measure body i.e. optic probe.
The Doppler signal received is sent to that photomultiplier is converted into electric signal and processing is concurrent big then at most general by receiving transducer
Recorded after strangling signal analyzer analyzing and processing to computer, corollary system software can carry out data processing work.In flow field
In the case of in the presence of appropriate trace particle, three direction speed of flowing can be measured simultaneously, and upgrading to after pda system even can be with
Measure the particle diameter of spherical shaped transparent particle.
PIV, i.e. particle image velocimetry method, be late nineteen seventies grow up a kind of transient state, multiple spot, touchless stream
Mechanics speed-measuring method.Constantly improve and development have been obtained in recent decades, have been above Single-point velocity determination skill the characteristics of PIV technologies
The limitation of art, velocity profile information that can be under same transient recording in a large amount of spatial points, and it is empty to provide abundant flow field
Between structure and flow behavior.For PIV technologies in addition to trace particle is spread to flow field, all measurement apparatus are simultaneously not involved in flow field.Separately
Outer PIV technologies have higher measurement accuracy.Due to the above-mentioned advantage of PIV technologies, it has also become current hydrodynamics measuring study
In heat subject, thus increasingly paid attention to.PIV speed-measuring methods have a variety of classification, the PIV of quovis modo, its speed
Measurement all relies on the trace particle that is dispersed in flow field, PIV methods test the speed all be by measure trace particle it is known very in short-term
Between interval in displacement come measure indirectly the instantaneous velocity in flow field distribution.If trace particle has sufficiently high flowing followability,
The motion of trace particle just can truly reflect the motion state in flow field.Therefore trace particle is very heavy in PIV velocimetries
Will.In PIV velocity measuring techniques, the trace particle requirement of high quality is：(1) it is as more consistent with Experimental Flowing Object as possible than important；(2)
Sufficiently small yardstick；(3) shape will justify as far as possible and size distribution is as uniform as possible；(4) there is sufficiently high light scattering efficiency.It is logical
Cenosphere or metal oxide particle are often used in liquid experiment, smog or dust granules are used in air experiment
(supersonic speed measurement uses nano particle), microchannel experiment uses fluorescent particles etc..When for liquid flow field survey, to tracer
The controllability of distribution situation and concentration of the particle in flow field proposes high requirement.Enter measured stream sowing trace particle
During field, uniformity coefficient and large effect can be produced to measurement result that trace particle is distributed in flow field, if skewness
The real information in tested flow field can not then be reflected, measurement result can be made to produce larger deviation, or even produce the measurement knot of mistake
Fruit.And when being directed to different Test Cycles, it is required to that concentration of the trace particle in tested flow field is adjusted at any time again,
And it is as brief as possible, rapid to adjust feedback procedure.
The advantages that PIV laser measurement technologies can measure the whole audience with it is widely used in the test in flow field.It is real in PIV
In testing, the selection of trace particle plays vital effect for the result of experiment.Trace particle must strictly have scattering
The ability of light and good followability, security, economy etc..
