Abstract

The goal of this research was to determine the impact of a pooled and flat stepped spillway on energy losses. FLOW3D, which is a computational fluid dynamics (CFD) program, with mesh size of 0.015 mm was used for this purpose. First, the code was tested against an available experimental model data for both water flow depth and inception point position. The outcome precisely shows agreement with the available laboratory work. Second, the energy dissipation and residual head of two different types of stepped spillways, flat and pool was computationally compared. The results show that in a pooled stepped spillway, energy dissipation is larger than in a flat step. In addition, the residual head reduces for pooled stepped chutes.
用计算流体力学研究池式和平阶式溢洪道对消能的影响
这项研究的目的是确定汇集式平台阶溢洪道对能量损失的影响。FLOW3D是一个计算流体动力学(CFD)程序,网格尺寸为0.015 mm。首先,针对水流深度和起始点位置的可用实验模型数据对代码进行了测试。这一结果与现有的实验室工作完全一致。其次,对两种不同类型的台阶式溢洪道(平式溢洪道和池式溢洪道)的消能和剩余水头进行了计算比较。结果表明,在汇集台阶溢洪道中,消能比在平台阶中大。此外,对于汇集的阶梯溜槽,残余水头会降低。
