The gate pump has recently received considerable attention as a type of effective drainage equipment. Air can be easily inhaled by the suction pipe, which could cause damage to the pumping system. Therefore, to improve the hydraulic performance of the gate pump, the flow behavior of the pump, including the pump-sump, must be investigated. This study focused on the investigation of the air entrainment and water flow behavior in the horizontal and elbow gate pump-sump models using a computational fluid dynamics analysis. A three-dimensional fluid domain of the horizontal and elbow gate pump models was constructed. Subsequently, the commercial code of ANSYS CFX was adopted to conduct numerical simulations. The unsteady simulations of the two-phase flow (air and water) were performed using the shear stress transport turbulence model. A total of six cases of numerical simulations were implemented. The details of the air-water two-phase flow characteristics in the pump-sump, including the pump models, were then investigated. The improvement of the air entrainment reduction using the elbow gate pump model was discussed.
