| Abstract: | In order to improve the volume efficiency of a Cycloidal pump, the internal flow field needs to be optimized to reduce the reflux and cavitations. With Computational Fluid Dynamics (CFD) method, numerical simulations of the internal flow field in a cycloidal pump were developed. It was analyzed what an effect the inlet and outlet cavities would have on volume efficiency of a pump. The simulation results showed that, for the inlet and outlet cavities in a cycloidal pump, reduction the G0 and enlarging the F0 properly would improve the distribution of the internal flow field, and then improve the volume efficiency. The conclusion of the simulations provided some reference for the structural design of a cycloidal pump. |
