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…
Adaptive criterion and modification of wave-particle decomposition in UGKWP method for high-speed flow simulation
Junzhe Cao, Yufeng Wei, Wenpei Long +2
Benefitting from the direct modeling of physical laws in a discretized space and the automatic decomposition of hydrodynamic waves and particles, the unified gas-kinetic wave-parti…
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…
An efficiency and memory-saving programming paradigm for the unified gas-kinetic scheme
Yue Zhang, Yufeng Wei, Wenpei Long +1
In recent years, non-equilibrium flows have gained significant attention in aerospace engineering and micro-electro-mechanical systems. The unified gas-kinetic scheme (UGKS) follow…
