Аннотация:This work studies plane transition (Kn=0.1–10) flow of a mixture of noble gases in the system, consisting of several rows of stretched filaments having different temperatures. Problem statement studying equilibrium state in closed system is considered. Calculations were performed using method of event-driven molecular dynamics (EDMD). It is shown that temperature difference leads to gas separation effect, which can be thereafter enhanced by increasing the number stages (rows of filaments).
