Abstract

The invention provides a particle image speed measuring device and a particle image testing method, and relates to the technical field of three-dimensional fluid field testing. The particle image speed measuring device comprises a laser system, an acquisition system, a synchronizing system and a data processing system, wherein the laser system is used for generating two light sources of which light wave vibration directions are perpendicular to each other; each light source radiates one cross section; the acquisition system is connected with the data processing system and is used for acquiring image data of particles on the cross sections and transmitting the image data to the data processing system; the synchronizing system is connected with the laser system and the acquisition system respectively, and used for controlling the laser system and the acquisition system to be switched on and off synchronously; and the data processing system is used for storing image data, and used for analyzing three-dimensional fluid field distribution according to the data image. The particle image speed measuring device is convenient to operate and control and accurate in testing result. Due to the particle image speed measuring device, the particle image testing method provided by the invention can be used for providing precise and reliable analysis testing results.

Description

technical field [0001] The invention relates to the technical field of three-dimensional flow field testing, in particular to a particle image velocity measuring device and a particle image testing method. Background technique [0002] As an important experimental means to study fluid motion, the flow field testing technology has a great promotion effect on the research of related disciplines. Particle Image Velocimetry (PIV) is a transient, non-contact, full-flow quantitative measurement technology developed in the 1980s. It combines the advantages of single-point measurement and flow display technology. It has high precision and high resolution, and can obtain the overall structure and transient average image of the plane flow field display. [0003] The latest foreign three-dimensional particle image velocimetry (SPIV for short) system uses stereo digital photography technology, that is, multiple cameras are used to record a section of the illuminated flow field from dif...
