Рост Плотности И Расхода Тяжелого Компонента При Истечении Разреженной Газовой Смеси В Вакуум

Abstract

Gas dynamics of a rarefied mixture flowing from a chamber into vacuum is studied for the case of disparate-mass components. The modeling was fulfilled by the DSMC method. An increase of the heavier component density is observed in the vicinity of the chamber’s outlet. A significant impact of the lighter component on the jet dynamics consists in an increase of the heavier component flux and direction of heavier particles to the axis.
