复式断面明渠水流三维数值模拟
3D Numerical Simulation for hydraulic characteristics of compound section of open channel
摘要
Abstract
The flow field structure of compound channel is more complex, this paper simulated the compound open-channel flows based on reynolds stress model (RSM) and finite volume method (FVM) and also used the coupled solver. It apply Roe averaged flux difference splitting (Roe -FDS) to discretizingflux. The comparison between numerical results and experimental data showed a very good agreement. Finally, the hydraulic characteristics of the cross - section of the compound channel was analyzed.关键词
