Investigation of a Negative Step Effect on Stilling Basin by Using CFD

Investigation of a Negative Step Effect on Stilling Basin by Using CFD

The negative-step stilling basin is an efficient and safe energy dissipator for high-head, large-unit discharge high-dam projects. However, studies of the effects of the negative step on the hydraulic performance of a high-dam stilling basin have not been conclusive. In the present study, a 2D RANS-...
