Computational fluid dynamic analysis of flow coefficient for pan check valve

摘要

This paper describes the computational fluid dynamic analysis of flow coefficient for pan check valve. This work is focused on determine the length of supporting beam by pressure drop analysis and evaluate flow coefficient. And then in case of design of pan check valve, predict flow head loss with different flow rate. The method of computational fluid dynamic analysis provides a greater insight into the flow visualization aspects through this pan check valve. By using computational fluid dynamic analysis, pressure and velocity description can be easily observed and the pressure drop and flow coefficient can be exactly predicted. The length of supporting beam gives an important effect on the fluid performance of the check valve and the optimum length for the supporting beam is 32mm, the pan disc supported at this distance yields the minimum pressure drop and maximum flow coefficient. This research improved the understanding of the fluid flow performance of check valve. The method can also be applied to design the other part of this valve and/or other different valves.
