Flow Patterns and Rectification Measures in the Forebay of Pumping Station

Abstract Due to land limitation, the forebay in the pumping station is generally not long enough, some disadvantageous flow patterns are easy to appear in the forebay, which is not beneficial to the safety and economic operation of the pump. In this paper, the flow pattern in the forebay of pumping station is taken as the research object, and we focus on the physical model test method, the analysis method of the flow pattern and the rectification measures such as beam, breast wall and column. At the same time, the research results show that the abovementioned rectification measures are helpful to improve the pumping station inlet conditions and operation reliability.
