Abstract

Six Navier-Stokes computations on the hypersonic flow over a 2D ramp are compared to one another and to experiments. The importance of grid density is clearly put into evidence as concerns the prediction of separation length. One computation on the flow over a 3D obstacle is compared with experiment.

Difficulties in achieving well-defined experimental conditions, particularly fully laminar conditions at reattachment, are discussed.
