An Overset Chimera Unstructured Grid Method and Its Applications

In this paper, an overset Chimera method is extended to unstructured mesh, the unstructured grid solver enhanced by the overset Chimera method is employed to various specific applications, in which time dependent fluid flows involving multiple moving bodies needs to be solved. The present method possesses not only the novel feature of Chimera method but also the advantage of unstructured grid approach. Its robustness and efficiency are illustrated in this paper through typical applications.
