AbstractThe inviscid flows over ONERA-M6 wing computed by the spectral volume (SV) and discontinuous Galerkin (DG) methods are compared with that given by the conventional cell-vertex finite volume scheme using the same unstructured tetrahedral grid. In comparison, solution accuracy, and computational cost are critically examined. It is shown that both SV and DG schemes can yield highly resolved shocked flows but their computational costs are substantially higher than that of the conventional finite volume scheme. Laminar boundary layer flow and turbulent flow over 3D flat plate are also computed. In particular, v velocity in laminar flowobtained by DG scheme using hybrid cell grid agree well with the Blasius solution even with less grid resolution.
