Abstract. We apply moment methods to obtaining an approximate analytical solution to Knudsen layers. Based on the hyperbolic regularized moment system for the Boltzmann equation with the Shakhov collision model, we derive a linearized hyperbolic moment system to model the scenario with the Knudsen layer vicinity to a solid wall with Maxwell boundary condition. We find that the reduced system is in an even-odd parity form that the reduced system proves to be well-posed under all accommodation…

Generalization of the Krook kinetic relaxation equation
One of the most significant achievements in rarefied gas theory in the last 20 years is the Krook model for the Boltzmann equation [1]. The Krook model relaxation equation retains all the features of
Principles of the Kinetic Theory of Gases
For the purposes of this article, the subject of the kinetic theory of gases is considered to be coextensive with the theory of the Boltzmann equation. We consider only the original equation of
Resolving Knudsen layer by high-order moment expansion
We model the Knudsen layer in Kramers’ problem by the linearized high-order hyperbolic moment system. Thanks to the hyperbolicity of the moment system, its boundary conditions are properly reduced
The temperature-jump problem in rarefied-gas dynamics
An analytical version of the discrete-ordinates method is used here to solve the classical temperature-jump problem based on the BGK model in rarefied-gas dynamics. In addition to a complete
A Framework on Moment Model Reduction for Kinetic Equation
TLDR
A uniform framework for the derivation of reduced models from general kinetic equations for the Boltzmann equation is proposed and the resulting model appears as a symmetric hyperbolic moment system.
Hyperbolic Model Reduction for Kinetic Equations
We make a brief historical review to the moment model reduction to the kinetic equations, particularly the Grad's moment method for Boltzmann equation. The focus is on the hyperbolicity of the
Slip/jump coefficients and Knudsen-layer corrections for the Shakhov model occurring in the generalized slip-flow theory
The slip/jump coefficients and the Knudsen-layer functions for the time-dependent version of the generalized slip-flow theory have been obtained for the Shakhov model up to the second order of the
A convergent method for linear half-space kinetic equations
We give a unified proof for the well-posedness of a class of linear half-space equations with general incoming data and construct a Galerkin method to numerically resolve this type of equations in a

TLDR
This paper considers low-speed problems with small gradients, and a linearized set of moment equations is derived to explore a classic temperature problem and can reliably capture all qualitative trends for the temperature-jump coefficient and the associated temperature defect in the thermal Knudsen layer.
