摘要

One of the main important goals of stilling basins is to provide a proper operation toward energy dissipation by creating hydraulic jump. Since, the experimental model usually involves spending time and money in present study numerical simulation using finite-volume software has been used to simulate Alborz dam in order to investigate the boundary layer hydraulic jump caused by the damper function in divergent rapids stilling basin of the dam. The results showed that using basin blocks have had positive effect on improvement of hydraulic jump performance and stabilized the jump in the basin. For higher values of Debi, the hydraulic jump tends to far away from the beginning of stilling basin and the flow behavior of rapids (a fast-flowing and turbulent part of the course of a river) surface affected by depth flow in stilling basin and indicate the latitudinal rapids function in the length in which the water level in the vicinity of the wall along the middle of the basin is rippling and bubbling due to the effects of turbulence and transverse waves move diagonally to the wall and boundary layer development on the side walls and too fast air entering in turbulent flows; while in the Debi, the entrance and air and water phase mixing and jump formation point is on the rapids which leads to stabilization of the submerged hydraulic jump within stilling basin in which water surface profile is concave and almost uniform.
