A kinetic analysis of hypersonic viscous flows of a polyatomic gas in a thin threedimensional shock layer
Abstract
Polyatomic gas flows in a thin threedimensinal shock layer are analyzed asymptotically for the case of hypersonic flows past blunt bodies using a kinetic equation for a gas with internal degrees of freedom. The applicability limits of a phenomenological description of hypersonic flows of a viscous gas based on a thin shock layer model are investigated; the physical meaning of the Newtonian transition in the limit in the NavierStokes and kinetic equations is analyzed. An asymptotic form is obtained for macroscopic equations associated with the Newtonian transition in the limit in an infinite chain of distribution function moments.
