Mathematical Modeling of Gas Effusion into a Vacuum

The effusion of gas through a small rectangular opening into a vacuum is studied using methods of mathematical modeling. The distribution functions of gas particles flowing out of an opening and the moments of these functions, i.e., fields of gas particle concentrations and velocities, are obtained....

Summary:The effusion of gas through a small rectangular opening into a vacuum is studied using methods of mathematical modeling. The distribution functions of gas particles flowing out of an opening and the moments of these functions, i.e., fields of gas particle concentrations and velocities, are obtained. The dependence of effusion on the volume from which the gas escapes is investigated.
