A Study of Electron Density Distribution in Viscous Flows

Abstract

The electron production for the viscous flow over a body in hypersonic flight and high altitudes has been studied and predictions of its magnitude have been made. The flight parameters selected for this study were typical of those encountered by the reentry nosecone experiments launched in a series of Air Force Cambridge Research Laboratories/Trailblazer 2 Rocket Flights. A chemical system appropriate for high temperature dissociated and ionized air has been utilized. In addition to NO+ the chemical kinetic system includes N2+, O2+, O+, N+. Both chemical and nonequilibrium effects are included. An evaluation of various wall conditions such as catalyticity and slip, of diffusion coefficients, and of magnitudes of various rate constants has also been considered.
