Determination of the effective probabilities of nitrogen atom recombination on materials from the results of experimental and numerical studies of heat transfer in electrodeless plasmatron jets
Abstract
Results of measurements of heat flows at the critical point of a cylindrical model with a catalytic end surface in subsonic jets of dissociated nitrogen generated by an induction plasmatron are compared with the results of a numerical study of nonequilibrium heat transfer for the experimental conditions at a pressure of 10 exp 4 - 3 x 10 exp 4 Pa. Based on the experimental and numerical data, the effective probabilities of the heterogeneous recombination of nitrogen atoms are determined for several metals at 300 K, for quartz at 700-1300 K, and for carbon and pyrographite at 1700-2200 K.
