説明
Numerical and experimental studies were done on unsteady flow in a pump sump to study the generation of air core vortex and submerged vortex, which cause vibration and acoustic noise. The geometry of the free surface in the test pump sump was visualized by Moire method, and velocities near pump suction were measured by PIV. Unsteady flow in the pump sump was calculated using VOF method in a commercial CFD software, and calculated velocities as well as free surface geometry were compared with measured ones. The present study showed that CFD can capture unsteady flow in a pump sump with a reasonable accuracy, and that the air core vortex as well as submerged vortex can be predicted by CFD.
