Abstract: Wall-attached vortices in pump intake commonly appear and damage the stability of the whole pump station. Revealing the effects of these vortices on the pump performance is crucial for safe operation. In this paper, ...

Abstract: In this paper, a new cubic subgrid-scale (SGS) model is proposed to capture the rotation effect. Different from the conventional nonlinear model with second-order term, the new model contains a cubic term which is originated ...

Abstract: An air-entrained vortex is a complicated and negative phenomenon in a pump sump. Due to the unsteady vortical and two-phase-flow properties, its prediction is challenging. In this paper, advanced turbulence models sensitive ...
