摘要

这些结构面临着一些挑战，例如在流动能量耗散过程中的空化和高速流动。溢洪道是用于通过大量流量的大坝的关键基本元件之一。目前的工作使用计算流体动力学（CFD）对阶梯式溢洪道和传统溢洪道的水面流量和压力分布进行了数值估计。用重整化群k-模型将数值结果与实验数据进行了比较。对数值数据和实验数据进行了比较，确定两组发现之间存在可接受的一致性。

Simulation of flow over stepped and traditional spillways

There are several challenges that are faced by these structures, such as cavitation and high speed of flow during the dissipation of flow energy. The spillway is one of the key basic elements of dams that are utilized to pass huge volumes of discharge. The current work used computational fluid dynamics (CFD) to numerically estimate the water surface flow and pressure distribution over stepped and traditional spillways. The numerical findings were compared with experimental data using the Renormalization group k- model. The numerical and experimental data have been compared, and it has been determined that there is an acceptable agreement between the two sets of findings.
