Abstract
HPCMP CREATE-AV Kestrel COFFE has been used to model three canonical shock problems: the viscous shock tube, the hypersonic circular cylinder, and the axisymmetric double cone. The viscous shock tube case was chosen to assess COFFE’s ability to model moving shocks and to compare results between several different temporal discretization methods. The hypersonic circular cylinder case was used to determine if the inviscid flux scheme within COFFE will induce the carbuncle phenomenon when applied to a supersonic bluff body problem. Finally the double cone case was run to evaluate COFFE’s performance on a problem involving complex flow fields created by a shock wave/boundary layer interaction. Many authors have run this case using two-dimensional axisymmetric grids with quadrilateral elements, but the presented results were generated using a fully three-dimensional grid containing only tetrahedral elements. This three-dimensional approach has indicated a possible circumferential instability in a flow field previously thought to be only axisymmetric.
