Abstract
In this paper, we propose an effective computational mathematical interpretation of the problem of the nonequilibrium flow of a polyatomic gas in a kinetic thin viscous shock layer near a blunt body in the plane of its symmetry. The correlation of flows in the kinetic and Navier–Stokes thin viscous shock layer on the frontal spreading line, which allows constructing the solution of the kinetic problem based entirely on the Navier–Stokes equations, is indicated. Using the proposed approach, heat transfer on the wall along the entire spreading line of a model of an aerospace aircraft of lifting-body type was numerically studied. The calculation results are compared with the data of the tunnel experiment.
