英文摘要 | a numerical model for shallow water flow has been developed based on the unsteady reynolds-averaged navier-stokes equations with the hydrodynamic pressure instead of hydrostatic pressure assumption. the equations are transformed into the sigma-coordinate system and the eddy viscosity is calculated with the standard k - epsilon turbulence model. the control volume method is used to discrete the equations, and the boundary conditions at the bed for shallow water models only include vertical diffusion terms expressed with wall functions. and the semi-implicit method for pressure linked equation arithmetic is adopted to solve the equations. the model is applied to the 2d vertical plane flow of a current over two steep-sided trenches for which experiment data are available for comparison and good agreement is obtained. and the model is used to predicting the flow in a channel with a steep-sided submerged breakwater at the bottom, and the streamline is drawn. |
