道路雨水口水力特性数值分析研究
Numerical Analysis of Hydraulic Characteristics of Road Rainwater Outfall
摘要
Abstract
The drainage of road rainwater outlet is often the object of single grate rainwater outlet,and there is a lack of research on multi-grate rainwater outlet.The three-dimensional hydrodynamic model of the rain-mouth was constructed,and the numerical simulation experiment of the rain-outlet model was carried out by Fluent,and the hydraulic characteristics of the rain-mouth were calculated and analyzed.The results show that the inlet flow of the rainwater outlet is all weir flow,and the multi-grate rainwater outlet mainly affects the side flow.With the increase of the inlet flow,the discharge efficiency of the same rainwater outlet has no obvious change,and the multi-grate rainwater outlet expands the water collection area by increasing the area of the side edge,thus affecting the discharge flow.The results can provide a new idea for the layout of urban rainwater outlets.关键词
