Burnett hypersonic thin shock layer near the windward side of a flat plate

Abstract

A one-layer model of a Burnett thin shock layer is simplified to fit the problem of a rarefied gas hypersonic flow along the windward side of a flat plate placed at a large angle of attack with an incident flow; here, the mathematical apparatus of the theory of a two-layer hypersonic thin viscous shock layer near nonthin bodies is used. This theory suggests that in the structure of a flow, between the followed body’s surface and the incident undisturbed flow, we have two typical regions-sublayers (a smeared pressure shock plus the shock layer proper). It is shown that the considered Burnett thin shock layer problem in the two-layer approximation completely reduces to the corresponding Navier-Stokes problem.
