The unified gas-kinetic scheme (UGKS) provides a framework for simulating multiscale
transport with the updates of both gas distribution function and macroscopic flow variables …

We propose a direct arbitrary Lagrangian-Eulerian (ALE) variant of the previously developed
discrete velocity method to solve the kinetic equation with the Bhatnagar–Gross–Krook …

We present a general framework for constructing trans-scale discrete Boltzmann models
(DBMs) for high-speed compressible flows ranging from continuum to transition regime. This …

In this paper, we extend the unified gas-kinetic wave-particle (UGKWP) methods to the multi-
species gas mixture and multiscale plasma transport. The construction of the scheme is …

In this paper we deal with the extension of the Fast Kinetic Scheme (FKS)(Dimarco and
Loubère, 2013 [26]) originally constructed for solving the BGK equation, to the more …

Multiscale nonequilibrium physics at large variations of local Knudsen number are
encountered in applications of aerospace engineering and micro-electro-mechanical …

This Element presents a unified computational fluid dynamics framework from rarefied to
continuum regimes. The framework is based on the direct modelling of flow physics in a …

The numerical study of one-dimensional gas expansion under pulsed evaporation into
vacuum is carried out on the basis of the direct simulation Monte Carlo method, the exact …

The discrete unified gas kinetic scheme (DUGKS) was originally developed for single-
species flows covering all the regimes, whereas the gas mixtures are more frequently …

The kinetic modeling and simulation of reactive flows, especially for those with detonation,
are further investigated. From the theoretical side, a new set of hydrodynamic equations are …
