This paper explores the possibility of using random vortex method to simulate gas-solid two-phase flow under high Reynolds number and proposes a physical model and algorithm of two-phase flow random vortex method. The problem of flow around cylinder in gas-solid two-phase flow was calculated. The calculated results are qualitatively consistent with the existing experimental results. In recent years, the numerical calculation of two-phase flow has received extensive attention both at home and abroad, and many two-phase flow models and numerical calculation methods have appeared. Each model has its scope of application. In this study, we propose to apply the random vortex method to solve the higher Reynolds number
