Multiphysics Simulations of Rarefied Gas Flows Using DSMC with Quasi-Nanbu Scheme

Abstract

In the previous papers, a new inter-molecular collision scheme “quasi-Nanbu scheme” has been developed and extended to diatomic molecules and gas mixtures in order to create a Direct Simulation Monte Carlo (DSMC) model on commercial FEM software COMSOL Multiphysics^®. In this work, two application examples, (i) conjugate heat transfer and (ii) hybrid DSMC/Test-particle simulation, are given to demonstrate multiphysics capabilities of the DSMC model.
