Abstract

The laminar, viscous, nonequilibrium flow around an axisymmetric blunt body has been computed. A fully implicit finite difference scheme of second order was used. The air was considered as a reactive mixture of the five species N2, O2, NO, N, O, in which the diatomic species, N2, O2 are in vibrational nonequilibrium. A range of Mach numbers from 14 to 18 has been investigated. The numerical results have been compared with those obtained by other workers and are in agreement with ballistic range data concerning the standoff shock distance at M = 15.35.
