The Effect of Sedimentation to The Pump Sump System by Using Computational Fluid Dynamics (CFD) Model

Abstract

Sedimentation is the one of the major problems in the operational of pump sump system. Therefore, study is conducted to determine the efficiency of pump sump due to sedimentation using ANSYS Fluent. Model simulation is conducted using different size of sediment and different water flow velocity to observed how it will effect on pump sump. The CFD model are well computed the sediment deposition in pump sump. Percentage of particle accumulate increased with increased of particle size but at lower velocity. While for sediment deposition area, most of the particle will be deposited at the inlet of the pump sump especially for larger particle.
