Abstract

In the pumping station engineering system, the inlet sump and inlet channels are very important components. Surface vortex, sidewall attached vortex and floor attached vortex of the pump sump is one of the important factors affecting the stable operation of the pump. In order to represent the influence of the vortex in the pump sump better, can construct the applicability model, model , model RNG ,model Realizable . Using these three different turbulence models to simulat and numerical calculate the inlet flow field can get more information and the related parameters about the position and intensity of vortex in the pump sump, to further comparative analysis of the forecasting result in different models. Through simulation analysis, the Realizable k- model predicts the locations and vorticity of free surface vortex, sidewall attached vortex and floor attached vortex more accurately than the other models, and the prediction of the tangent velocity and the circular rector is more consistent with the test value, which can provide reliable basis for the design and optimization of the pump sump.
