Abstract:

Study was continued on the nonequilibrium phenomena in rocket nozzles. Theoretical calculations of recombination dissociation processes of homonuclear diatomic molecules were made according to the theory of Benson and Fueno Douglas Aircraft Co. Engineering Paper No. 1265. The theory of absolute reaction rates was pursued, employing methods devised by Sato J. Chem. Phy., 2359219552465 and Eyring Glasstone, Laidler, and Eyring, The Theory of Rate Processes McGrawHill Bools Co., Inc., New York, 1951 for the construction of potential energy surfaces. Refinements in the experimental shock tube facility are discussed and the results of preliminary tests of the side-wall rapid-expansion system are illustrated. A review of theoretical and experimental considerations for a recently initiated flash photolysis facility is presented. The performance of a catalytic surface atom concentration probe in hypersonic nonequilibrium flows was evaluated and the operation regimes for the probe in a glow discharge facility defined. Author
