Analysis and Optimization of Flow Pattern in Inlet Passage of Pumping Station

Abstract

Compared RNG and Realizable model with experiment results in numerical simulation in inlet passage，conclusion Realizable k-e model is better reasonable in simulation can be pertained. In order to obtain ideal flow pattern ,Realizable k-e model could be using to simulate the passage and analyze flow pattern. Based on the simulation passage configuration can be modified to pursue ideal flow pattern, which can result in ideal inlet of pump and improve pump operating condition, vibration and noise in pumping station. Inlet passage flow pattern can be modified by using triangle piers,comparing different configuration can obtain the ideal results.
