| Abstract | ||||
| The swing check valve (SCV) is a type of check valves or non-return valves that allows the fluid to flow in one direction only. The main goal of this research is devoted to enhance the SCV performance by accelerating the SCV closure, thus reducing the amount of reversed flow through the valve before it is fully closed. This will be carried out only by modifying the design of the SCV itself and without using any external devices like springs or external attached masses. A wafer type SCV is used as a case study to investigate its transient closing characteristics; flapper’s angle, reversed flow through the SCV and pressure rise due to the valve closure. With the aid of numerical simulation, five of ten suggested modifications are chosen and 3D printed to be tested experimentally versus the original/reference design. The experimental investigation shows that two of the five designs close faster with less reversed flow than the original/basic design. | ||||
