摘要
A three-dimensional non-hydrostatic numerical model for simulation of the unsteady free-surface stratified flows is presented. The model is based on the 3D Reynolds-averaged Navier-Stokes equations for Boussinesq fluid. The model equations in the vertical sigma-coordinate system are integrated with mode splitting technique and decomposition of pressure and velocity fields on hydrostatic and non-hydrostatic components. The model is validated against several applications that show the importance of the non-hydrostatic effects.
