双层悬栅消力池的水力特性数值模拟
Numerical simulation for hydraulic characteristics of double suspended grid in the stilling basin
摘要
Abstract
Through physical model experiment, it is hard to get detailed hydraulic parameter data such as velocity, pressure, etc. To cope, t he paper uses fluid dynamics software FLUENT to set up RNG k- ε double-equation turbulence model to make nu-merical simulation, so as to get hydraulic parameters such as maximal water dept h, flow pattern, velocity and pressure, et c. Then makes analysis of comparison betw een mat hematical model calculat ed value and physical model experimental value, and makes a-nalysis of comparison among numerical model calculated values. T he result show s the mat hematical model calculated value and physical model experimental value are roughly identical, and the error between calculated value and experimental value is small when double suspended grid is arranged. The double suspended grid has st rong capacit y to make current generate swirl, hence small impact on apron slab by current , and low ered surge at the apron slab, larger eff ect on the pressure change, which show s double suspended grid has better performance in eliminating wave and stabilizing current.关键词
