A Mathematical Description of Gas-Surface Interaction Based upon Reciprocity

Abstract

The general problem of the interaction between a monatomic gas and a solid surface is investigated from a mathematical point of view by the use of a scattering kernel. This general scattering kernel must fulfill the obvious conditions of normalization and non-negativity and has recently been shown to also satisfy the condition of detailed balancing or reciprocity. It is shown that calculated parameters are related to a tangential and a normal thermal accommodation coefficient. The scattering kernels obtained are integrated, in some cases analytically and others numerically, with various weighting functions in order to obtain mean reflected properties, both global and local, such as molecular flux, speed, and energy. These various results are presented for typical gas-surface interaction parameters.
