Finite-Difference Solutions for Nonequilibrium Laminar Boundary Layers in Ionizing-Argon Flows.

Abstract

Details are given of an implicit six-point finite-difference scheme for solving two-temperature chemical nonequilibrium laminar boundary-layer flows in ionizing argon. The analysis extends previous work by considering the radiation-energy loss and the chemical reactions in the plasma of the ionizing boundary layer. The variations of transport properties based on the known elastic-scattering cross-sections for an argon plasma across the boundary layer are considered. The effects of the chemical reactions, radiation-energy loss and the electric sheath on the boundary-layer structures are discussed.
