AN APPROXIMATE ANALYSIS OF THE CONTINUUM LOW DENSITY HYPERSONIC FLOW OF A CHEMICALLY REACTING AND RADIATING GAS OVER A BLUNT NOSED BODY

Abstract

The continuum low density hypersonic flow of a chemically reacting and radiating gas over a blunt body is analyzed by an approximate technique based on a recent alternative formulation of the well-known method of integral relations. Specifically, approximations are introduced for the streamwise variations of several flow properties, while detailed radial profiles, (consistent with the stipulated procedure) are sought by numerical analysis along normals to the body (essentially normals to streamlines); the particular formulation allows careful analysis of the large changes in physicochemical properties of the gas between body and shock, as are to be encountered at the low Reynolds numbers where viscous effects are important over the entire shock layer. Detailed derivations of the simplified system of ordinary differential equations and of the boundary conditions governing the problem is presented. An outline of numerical procedures for aplications is also given.
