| Abstract: | This paper is concerned with the numerical solution of turbulent flows on the concave surfaces of spillway dams. Orthogonal curvilinear coordinates are used to deal with the complicated computational region and the effects of streamline curvature on turbulent flows are included. The SIMPLEC procedure has been used for the transformed governing equations in the transformed domain. The comparison between computed results and experimental data shows a satisfactory agreement. |
