INVARIANT IMBEDDING AND RAREFIED GAS DYNAMICS [PDF]
Proceedings of the National Academy of Sciences, 1963 Invariance principles and invariant imbedding techniques are applied to representative problems in the kinetic theory of gases. The problem of plane shear flow between two infinite flat plates is used to present the ideas of invariant imbedding in the context of rarefied gas dynamics.

A Discrete-Ordinates Solution for the Strong Evaporation Problem in Rarefied Gas Dynamics
Trends in Computational and Applied Mathematics, 2021 In this work we solve the nonlinear strong evaporation problem in rarefied gas dynamics. The analysis is based on the BGK model, with three dimensional velocity vector, derived from the Boltzmann equation. We present the complete development of a closed

The effect of system boundaries on the mean free path for confined gases
AIP Advances, 2013 The mean free path of rarefied gases is accurately determined using Molecular Dynamics simulations. The simulations are carried out on isothermal argon gas (Lennard-Jones fluid) over a range of rarefaction levels under various confinements (unbounded gas,
