摘　　要：设计了一种高效的混合网格聚合方法,在此基础上应用多重网格技术来加速Navier-Stokes方程的收敛过程。方程求解采用Jam son的中心格式有限体积法。对NACA0012翼型和ONERA M6机翼的粘性绕流进行了数值模拟,算例结果与试验结果符合良好,加速收敛效果显著。In the paper, an efficient method is designed to convergence hybrid meshes, and the multigrid algorithm has been developed to accelerate the Navier-Stokes equation to a steady state. The Jamsonfinite volume method is used for the calculation of the flow. As an example, the computational results of viscid flow field around NACA0012 airfoil and ONERA M6 wing are in a good agreement with the experimental data, all results confirm the high efficiency of multigrids.
