Phenomenological energy exchange of diatomic gases: Comparison of Pullin and Borgnakke-Larsen models in direct simulation Monte Carlo method
Hao Jin, Sha Liu, Ningchao Ding +4
In hypersonic rarefied flows, insufficient intermolecular collisions cause significant deviations between translational and rotational temperatures, leading to strong thermal noneq…

A novel Cercignani-Lampis boundary model for discrete velocity methods in predicting rarefied and multi-scale flows
Jianfeng Chen, Sha Liu, Rui Zhang +5
To extend the discrete velocity method (DVM) and unified methods to more realistic boundary conditions, a Cercignani-Lampis (CL) boundary with different momentum and thermal energy…
