%X In order to deeply understand the mechanical mechanism of sand particles movement,it is fundamental to acquire both instantaneous sand particles velocity and instantaneous airflow velocity simultaneously during wind tunnel test.This paper developed a segmentation method of two-phase flow PIV images based on MATLAB platform.The fundamental principle of this method lies in distinguishing sand particles from airflow tracing particles by particles' sizes of two-phase flow PIV images.This method can clearly segm...
