Unified gas-kinetic wave-particle method for multi-scale phonon transport
Hongyu Liu, Xiaojian Yang, Chuang Zhang +2
Over the past 7 decades, the classical Monte Carlo method has played a huge role in the fields of rarefied gas flow and micro/nano scale heat transfer, but it also has shortcomings…
Wave-Particle Based Multiscale Modeling and Simulation of Non-equilibrium Turbulent Flows
Xiaojian Yang, Kun Xu
This paper presents a novel methodology for the direct numerical modeling and simulation of turbulent flows. The kinetic model equation is firstly extended to turbulent flow with t…
Radiative hydrodynamic equations with nonequilibrium radiative transfer
Mingyu Quan, Xiaojian Yang, Yufeng Wei +1
This paper presents a kinetic model for the coupled evolution of radiation, electrons, and ions in a radiation plasma system. The model is solved using two methods. The gas-kinetic…
