A Multi-Scale Boltzmann Equation for Complex Systems of Neutral Gases across All Flow Regimes
Sha Liu, Junzhe Cao, Sirui Yang +1
A Multi-scale Boltzmann Equation (MBE) is found from the gas-kinetic theory and the direct modeling philosophy as a master equation for complex physical systems of neutral gases ac…
