| 摘 要： | 复式断面渠道水流流场结构比较复杂,本文用耦合式求解器对复式断面明渠水流的三维流场进行了模拟.采用交错网格,界面上的动量差值采用Roe格式,紊流数学模型选用雷诺应力模型.将计算结果与实验结果进行比较,两者的吻合度较好,从而验证了数学模型的可靠性,最后又对复式断面明渠横剖面上水流运动特性进行了分析.

| 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 discretizing flux.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. |

| Keywords: | compound section of open channel coupled solver Roe-FDS secondary flow |
