Applications of new boundary conditions for the Boltzmann equation derived from a kinetic model of gas-surface interaction
New boundary conditions for the Boltzmann equation proposed recently by the authors based on a kinetic model of gas-surface interactions are applied to three basic problems of a rarefied gas between two parallel plates: the heat-transfer between the plates, plane Couette flow, and plane Poiseuille flow driven by an external force. The results are compared with those based on the conventional Maxwell-type condition including the diffuse reflection. The effects of parameters characterizing gas-surface interactions in the above basic problems are clarified.
