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