Numerical Modeling of Liquid Flow in a Pump Station

详细

Amathematical model is presented for two-phase flow in a pump station. The model is based on three-dimensional non-steady-state Reynolds equations. Turbulence is modeled using the standard k-ω SST model. Two-phase flow is calculated by the VOF method. Analyses of liquid behavior are presented under different initial liquid levels in the station. A optimum value for the initial liquid level is obtained. Areas of vortex formation are shown when the liquid level deviates from the recommended value. The effectiveness of the given pump station design is confirmed.
