Numerical Simulation of Flow Through Sump Pump

In sump and intake models, the usual aim is to achieve smooth, steady approach flow conditions so that obstructions and velocities are high enough to cause air entrainment. By a proper intake sump design, uniform flow can be led to the vertical pumps and the performance of the pump in fact enhanced. The Hydraulic Institute Standards specify general guidelines for the design of sumps. The site constraints usually call for a deviation from the Standards. It then becomes essential to investigate the sump to ensure smooth flow over the entire flow range of the pumps. The study on swirling flow in sump with multiple pump intakes of rectangular and circular pump intake structure, and it has been observed that the location and operating conditions of the suction pipe in sump geometry affect local and global intake performance parameters significantly.
