Quasi-Nanbu Scheme Extended to Diatomic Molecules and Gas Mixtures

Abstract

Quasi-Nanbu scheme, a new inter-molecular collision scheme proposed in the previous work, has been extended to diatomic molecules and gas mixtures. Then, the extension has been implemented in a Direct Simulation Monte Carlo (DSMC) model created on a commercial FEM software COMSOL Multiphysics^®. N₂ gas heat conduction between parallel plates and two-dimensional supersonic nozzle flows of gas mixtures are demonstrated as application examples.
