Gas Micro-Flow Modelling Based on Regularized 13-Moment-Equations
TL;DR: In this paper, a combination of the Chapman-Enskog expansion and Grad's moment method in kinetic theory of gases yields the Regularized 13Moment Equations (R13 equations).
Deterministic numerical solutions of the space-inhomogeneous Boltzmann equation using the fast spectral method
TL;DR: In this article, the fast spectral method was extended to deal with other collision kernels, such as those corresponding to the soft, Lennard-Jones, and rigid attracting potentials, and the numerical results indicated that di↵erent forms of the collision kernels can be used as long as the shear viscosity (not only the value, but also its temperature dependence) is recovered.

TL;DR: In this paper, a generalized physics-based expression for the drag coefficient of spherical particles moving in a fluid is derived, which incorporates essential rarefied physics, low-speed hydrodynamics, and shock-wave physics to accurately model the particle-drag force for a wide range of Mach and Knudsen numbers (and therefore Reynolds number) a particle may experience.

Efficient simulation of rarefied gas flow past a particle: A boundary element method for the linearized G13 equations
TL;DR: In this article, a boundary integral formulation for the steady linearized form of Grad's 13-moment (G13) equations applied to a uniform flow of rarefied gas past solid objects at low Mach numbers is developed.
