Modeling flow in a shock viscous layer

This paper considers the two-dimensional problem of high-velocity translational-nonequilibrium flow of a monatomic gas past a surface which was formulated in the theory of viscous hypersonic flows based on macrokinetic 13-moment Grad equations using the approximation of a two-layer thin viscous shock layer (TVSL) near non-thin bodies. A class of similarity variables is proposed that allows the kinetic problem of a TVSL to be reduced to the well-studied Navier-Stokes problem of a TVSL.
