The model study was conducted to evaluate the characteristics of flow in the sump and pump intakes and to develop modifications required for reducing swirl in the flow approaching the pump intake. The three pumps were fitted with formed suction intakes (FSI). The 1:11-scale model indicated the need for a minor modification (baffles in the sump) to reduce current circulation in the sump, thereby reducing swirl in the flow approaching the pump propeller. For all anticipated flow conditions, the recommended sump design will enable the FSIs to deliver stable and evenly distributed flow to the pump propellers.
