Unified Gas-Kinetic Scheme for Unsteady Multiscale Flows with Moving Boundaries
Yue Zhang, Wenpei Long, Junzhe Cao +1
Simulating multiscale flows with moving boundaries, such as hypersonic multi-body separation and flows in micro-electro-mechanical systems (MEMS), requires robust numerical methods…
The study of coherent Rayleigh-Brillouin scattering in multiple flow regimes using unified gas-kinetic scheme
Xiaozhe Xi, Junzhe Cao, Kun Xu
Coherent Rayleigh-Brillouin scattering (CRBS) holds great promise for the characterization of gas properties and the investigation of gas kinetic processes. The CRBS spectrum exhib…
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…
Unified gas-kinetic scheme for reactive flow with multi-scale transport and chemical non-equilibrium
Yufeng Wei, Junzhe Cao, Kun Xu
Reactive flows for rarefied gas mixtures involve a multi-scale transport characterized by particle collisions and free streaming, and non-equilibrium physics containing multi-speci…
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…
