Statistical Model for Molecular Internal Energy Exchange in DSMC Method for Rarefied Flow Analysis

抄録

New statistical direct simulation Monte Carlo model for internal energy exchange for molecules is proposed. The derivation of the model is based on the inelastic collision cross section which ensures the relation of detailed balance at equilibrium between microscopic states. It is shown that the present derivation method gives us a general frame-work to generate various models for the inelastic collision. The present derivation method can generate not only the present internal energy exchange model but also the Koura's inelastic cross-section model. The present internal energy exchange model was applied to an adiabatic thermal relaxation problem in a stationary reservoir and was compared with Koura's statistical inelastic cross-section model.
