In dilute fluid-solid two phase flow, particle motion in sudden contraction and sudden expansion structure is studied. CFX is used to simulate both fluid field and particle motion. Four different turbulence models are compared with each other and k-e model is proved to be efficient to calculate this situation. Four different particle injection regions are set to observe particle motion. The influence of particle diameter and virtual mass force are studied, separately.
