For understanding the behavior of a gas close to a channel wall it is important to model the
gas-wall interactions as detailed as possible. When using molecular dynamics simulations …

In rarefied gas flows, discontinuity phenomena such as velocity slip and temperature jump
commonly appear in the gas layer adjacent to a solid boundary. Due to the physical …

Revealing the scattering behaviour of gas molecules on porous surfaces is essential to
develop accurate boundary conditions for kinetic transport models that describe the gas …

A theoretical derivation of slip boundary conditions for single-species gas and binary gas
mixture based on two typical gas-surface scattering kernels is presented. If the Maxwell …

In this study, we develop and assess a new approach to modeling slip boundary conditions
in gas mixtures with coupled state-to-state vibrational-chemical kinetics and surface physical …

The scattering behaviors of nitrogen molecules reflected at a platinum surface are studied by
the molecular dynamics method for the gas-surface interaction. The platinum surface is …

Empirical gas–surface interaction models, such as the Maxwell model and the Cercignani–
Lampis model, are widely used as the boundary condition in rarefied gas flow simulations …

This work proposes a new stochastic gas–solid scattering model for diatomic gas molecules
constructed based on the collisional data obtained from molecular dynamics (MD) …

This article presents a model of a scattering kernel of boundary conditions for the Boltzmann
equation. The proposed scattering kernel is based on an anisotropic accommodation …

A kinetic theory describing chemical reactions on crystal surfaces is introduced. Kinetic
equations are used to model physisorbed-gas particles and chemisorbed particles …
