WEAKLY IONIZED NONEQUILIBRIUM VISCOUS SHOCK LAYER AND ELECTROSTATIC PROBE CHARACTERISTICS,
Abstract
The electro-chemical interactions between the hypersonic stream of weakly ionized gases and the stagnation region of electrically biased blunt bodies are analyzed. The analysis is based on a continuum description. From the study, typical current-potential relationships for electrostatic stagnation probes are obtained. The effects on the electrical characteristics of the finite rate collisional energy exchange between electrons and neutrals, and the nonequilibrium electron-ion recombination are studied. Particular attention is given to the electron temperature variations in the free stream, shock, and the shock layer. Among other things, it was found that the classical electron saturation current is not usually attained. (Author)
