【 摘 要 】

An initial CFD model which was based on an active rotary cross-flow membrane separation device was established. Fluent commercial software was used to carry out numerical simulation of the two axis membrane disk device. It was found that as the inflow velocity increased, the particle residence time decreased and gradually became stable. Therefore, controlling the inflow velocity can improve the load of diaphragm and the efficiency of purification.
