| 摘 要： | 发展建立了用于多体分离等包含动边界的非定常流场数值模拟方法,建立了笛卡尔坐标系下边界以任意速度运动的控制体上的流动控制方程,结合几何守恒律确定网格速度,发展了基于结构网格的动网格方法,网格移动量采用加权插值方法得到.通过数值模拟二维翼型及三维机翼的强迫振荡非定常流场,表明该方法可以数值模拟包含动边界的非定常流场.

| Abstract: | 3D time-accurate Euler/Navier-Stocks equations for a cell with moving boundaries are established in a Cartesian framework.Based on the two-order Godunov scheme,numerical simulation methods on dynamic grids are established.To avoid grid motion induced error,the geometric conservation law(GCL) is satisfied numerically.The method is applied to simulate unsteady transonic flow about an oscillating airfoil(2-D) and an oscillating rigid rectangular wing(3-D).Computational results are in good agreement with the experimental data.The methods are effective and can be used to solve multi-body separate problems. |
