Application of Simultaneous PIV and PLIF in Study of Flow Field System

Abstract

: As a synchronous measurement technique for flow-field velocity and scalar measurements, PIV-PLIF (Particle Image Velocimetry-Planar Laser Induced Fluorescence) can provide detailed data support for complex flow with unsteady and strong three-dimensional space. The development and application of this technology in home and abroad in recent years are comprehensively reviewed. We first introduce the origin and working principle of particle image velocimetry technology and planar laser-induced fluorescence technology, and then discuss the current research status of PIV-PLIF, and then show the typical application of PIV-PLIF synchronous measurement method in engineering application. Finally, the application prospect and development trend of PIV-PLIF synchronous measurement technology are discussed. The combination of image velocimetry and planar laser-induced fluorescence is a trend of experimental hydrodynamics.
