Multiphase flow in reactor involves complex flow,mixing and mass transfer processes,and it is an important research object in chemical engineering.Particle image velocimetry(PIV)is a new experimental technique for multiphase flow field measurement and visualization in recent years.It has been widely used in multiphase flow field detection because of its significant advantages such as transient,multi-point and non-invasive measurement.This paper summarizes the latest progress in the application of PIV technology from the perspective of multi-phase and multi-scale,and extracts the technical problems and corresponding solutions in liquid-liquid mixing,solid-liquid mixing,gas-solid flow and gas-liquid flow,which is expected to provide reference for the potential application of PIV technology in multi-phase systems.
