A second-order unified gas-kinetic wave-particle method with enhanced mesh independence for hypersonic flows
Junzhe Cao, Rui Zhang, Wenpei Long +2
Benefiting from the direct modeling of physical laws in a discretized space and the automatic decomposition of the gas distribution function into hydrodynamic waves and particles,…
A unified gas-kinetic wave-particle method for multiscale binary-species gas mixtures
Junzhe Cao, Yufeng Wei, Wenpei Long +2
This paper presents a unified gas-kinetic wave-particle (UGKWP) method for simulating multiscale binary-species gas mixtures. Benefiting from direct modeling in a discretized space…
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 simplified unified wave-particle method for diatomic gases with rotational and vibrational non-equilibrium
Sirui Yang, Chengwen Zhong, Ningchao Ding +4
The hypersonic flow around near-space vehicles constitutes a multi-scale flow problem. Due to insufficient molecular collisions to achieve equilibrium, rarefied gas effects are pre…
Simplified unified wave-particle method for diatomic gases based on Rykov model
Sirui Yang, Sha Liu, Junzhe Cao +1
During the past decades, the numerical methods based on Navier-Stokes (N-S) equations and direct simulation Monte Carlo (DSMC) methods have been proved effective in simulating flow…
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…
