Experimental Study And Numerical Simulation Of The Flaring Gate Pier＆Stilling Basin United Energy Dissipater With High Water Head And Large Discharge

The hydropower station presented in this paper is one of the highest dam projectadopted “flaring gate pier＆stilling basin” united hydraulic engineering dissipaterin China,which provided with the characters of the hydro project.The RNGk–εturbulent modeling with VOF method was used to3D Numerical Simulation ofhydraulic characters of the flaring gate pier＆stilling basin united energydissipater with high water head and large discharge,which was served for shapeoptimization of hydraulic engineering application.The calculated result agreed verywell with the physical modeling experimental data.The results of this study successfully solve the water conservancy energydissipator Body (deep pool, pool length) and the effect of energy dissipation andother practical problems, a deeper look into the hydraulic characteristics of flaringpier joint energy dissipator, improve the rate of energy dissipation and reduceengineeringthe significance of the cost, at the same time to provide a reference forsimilar engineering design and physical model test.
