Hypersonic Viscous Flow

Abstract

Research and documented works on Viscous hypersonic flow theory are summarized and reported. Topic areas where the research has been focused are: (1) a fully viscous version of the shock layer (VSL) and its extension beyond the Navier-Stokes (NS) level based on Grad's thirteen moment equations and (2) inviscid-viscous iteration in hypersonic flows. The development in area 1 has led to a principle which allows correlation of shock layer flow far from translational equilibrium with a corresponding flow based on the NS equations, as substantiated by extensive comparison of direct simulation Monte Carlo and NS-based calculations. The development in area 2 resulted in a triple-deck theory of hypersonic boundary layer under strong wall cooling which exhibits drastically different structure and properties of the triple-deck.
