The efficiency of the flow mixed pump installed within the bell-mouth in the sump is reduced by the flow characteristics of around intakes. Strong submerged vorticies can be successfully suppressed by installing an AVD(anti-submerged vortex device) on the bottom of pump intake channel just below the bell-mouth. Sump model with AVD device basin is designed and the characteristics of submerged vortex is investigated in the flow field by numerical simulation. In this study, a commercial CFD code is used to predict the efficiency of the pump with the AVD installation in the pump station accurately. |
