Collision Models in the Hawk DSMC Implementation

Abstract

This paper presents a series of tests that have been conducted to validate the collision models of the Hawk DSMC implementation. These tests cover the hard sphere (HS), variable hard sphere (VHS), and variable soft sphere (VSS) collision models, and the Larsen- Borgnalkke energy exchange model, for non-reacting gas mixtures. The results show that Hawk obtains the correct results in all cases under consideration.
