SOME EFFECTS RELATED TO THE MULTICOMPONENT NATURE OF GAS MIXTURES,

Abstract

Consideration is given to the flow past an impenetrable surface of a mixture of two extraneous gases, one of which consists of two-atom molecules and can dissociate into atoms. It has been shown that the difference in the coef ficients of diffusion of the separate components lead to a diffusion breakdown of the mixture of gases. Results are presented of the numerical solution for air considered as a gas of three components, O, O2, and N2. Analogous results are presented for five-component air with the addition of nitrogen and nitrogen oxide. On the basis of the numerical solutions, there are determined Lewis's numbers computed in accordance with generalized coefficients of diffusion. It is shown that inside the boundary layer Lewis's generalized number for molecular nitrogen changes from-infinity to + infinity.
