【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.更多还原
