Abstract :
The flow in a pump sump is a very complicated one, which has three dimensional flow patterns, deformed free surface, and many unsteady vortices. As the model testing has a problem of similarity, CFD simulation method attracts attention in these days. In this study, a model case flow in the pump sump with simplified shape is simulated numerically. The flow is simulated as three-dimensional with free surface. Using different grid structures and boundary conditions, the result is compared each other and also compared with an experiment [1].
