天然河流流场数值模拟的预处理方法

NUMERICAL SIMULATION OF NArURAL RIVER FLOW BY THE PRECONDITIONING METHOD

  • 摘要: 提出了求解一种二维原始变量湍流模型方程组的预处理方法。应用此方法对驱动方腔内的涡流及天然河流流场作了数值模拟计算,结果表明预处理方法具有较好的稳定性及较快的收敛速度,对天然河流流场的计算只有实用价值。

     

    Abstract: A preconditioning method is presented for solving 2-Dturbulent floWmodel.By using this method,numerical simulations of driven square cavity flow and naturalriver flow are performed.The numerical results show that the method has good stabilityand fast convergence.
