| 摘 要： | 应用多重网格区域分裂并行计算方法研究具有壁面Weis-Fogh机构绕流，将二维物理平面流动区域变换为矩形区域，推导出流函数的多重网格差分计算格式，编制出并行计算程序。全部计算在英国London大学ITL并行计算中心完成。结果表明，多重网格并行计算具有较高的加速比，绕机翼的环量计算值与理论吻合。

| Abstract: | This paper considers a multigrid parallel numerical algorithm of the Weis-Fogh mechanism moved in a channel. We map the physical flow domain into a square domain, and derive the multigrid difference formula of the control equation. The numerical results show that our parallel algorithm has high speedup, and that the circulation calculated is compared well with theoretical one. |
