Kinetic
description of a supersonic impulse jet expanding into vacuum. II. Mixtures of
monoatomic gases
Abstract
On the basis of Boltzmann kinetic equation, the model of
impulse jet expansion of a monoatomic gas mixture has been constructed. The
Boltzmann equation has been solved by the Grad method. For analysis of a moment
equation system, the method of matching of asymptotic expansions was used. The
velocity slips and temperature differences depending on the source conditions
and the concentrations of components of a mixture were obtained. The functional
connection between these magnitudes and the interaction potential form was also
determined.
