A pump sump is an indispensable facility in cargo ships, irrigation, drainage, agriculture and industrial processes. The water intake conditions around suction bell mouth significantly affect the performance of the whole pumping system. However, there are different types of undesirable vortices that occur in pump sump, such as submerged vortex and air entraining vortex. Accompanying with the variety of vortex, noise and vibration also appears. In this study, a scaled down model of a pump sump was designed and constructed. The occurrence of the vortex was the concentrated target which was investigated under various suction pipe inlet conditions. With different water levels, flow rates and a fixed distance from the bottom to suction pipe bell mouth, detailed experiments were conducted. Additionally, a computational fluid dynamics (CFD) analysis was performed, verifying the influence of water level and flow rate on visualization and formation of vortex obtained in the experiment. The CFD analysis results were compared with those of the experiment.
