蜗形滞流器结构尺寸对其外特性影响规律的三维数值模拟
3-D numerical simulation on law of influence from structural size of hydro-brake on its externalcharacteristics
摘要
Abstract
Hydro-brake can effectively improve the phenomenon of urban water-logging,which is already widely used in the European and American countries,but the core technique of it is rarely reported at home and abroad,thus it is not widely popularized and applied in China.By taking the study of the law of the influence from the structural size of hydro-brake on its external characteristics as the objective,the types of the hydro-brake with the detention radiuses of 300mm,450mm,600mm,750mm,etc.are selected for carrying out the 3-D numerical simulation with VOF model.The result shows that the influence from the structural size on the external characteristics of the hydro-brake is not a linear relationship.For the hydro-brakes with the same detention radiuses,their inlet sizes directly influence their external characteristics,moreover,the influences from their widths are larger than the influences from their heights,while the external characteristics of the hydro-brakes with different radiuses are also different,but their trends are consistent.It is found out through the relevant comparison that the hydro-brake with the radius of 430mm can generate the highest detention efficiency.The study result has a certain reference value for the popularization and application of the hydro-brake to urban water-logging control.关键词
