【Abstract】 Depth averaged k ε turbulent model, boundary fitted coordinate system and stagger grids are adopted to solve the Reynolds equation and contaminant transport diffusion equation by finite volume mthod. Several typical outlets along the banks of the Chongqing region in The Three Gorges Reservoir are selected, and their mixing zones are computed under different conditions, then a practical computational method is brought forward.更多还原
