用插值元法按N.S方程计算二维明渠高雷诺数紊流(带自由面的回流)

2-D Simulation of Open Channel Turbulent Flow with High Reynold Number by Employing N. S Equations and IEM

我们从1986年开始研究按N.S方程直接计算明渠紊流,以计算明渠扩展段回流为重点,雷诺数高达10~7(Re=(V_0·h_0)/γ,v=10^(-6)m^2/s),今天终于取得了突破,获得了真实的生动的紊流流态,与水工模型试验结果一致,希望引起大家的兴趣。

Since 1986, We have been studying the topic of simulating open channel turbulent flow, esoecially for backflow in extended section, by directly employing N. S equations. Now a breadkthrough is gained. The simulated turbulent flow pattern is realistic and lively, and has a good agreement with physical model test results, which is expected to arise the interests of other researchers.
