Slip and Jump Coefficients for General Gas-Surface Interactions According to the Moment Method

Ruo Li, Yichen Yang

We develop a moment method based on the Hermite series of arbitrary order to calculate viscous-slip, thermal-slip, and temperature-jump coefficients for general gas-surface scatter…

Construction of boundary conditions for Navier-Stokes equations from the moment system

Ruo Li, Yichen Yang, Yizhou Zhou

This work concerns with boundary conditions (BCs) of the linearized moment system for rarefied gases. As the Knudsen number is sufficiently small, we analyze the boundary-layer beh…

On Well-posed Boundary Conditions for the Linear Non-homogeneous Moment Equations in Half-space

Ruo Li, Yichen Yang

We propose a necessary and sufficient condition for the well-posedness of the linear non-homogeneous Grad moment equations in half-space. The Grad moment system is based on Hermite…

Linear Moment Models to Approximate Knudsen Layers

Ruo Li, Yichen Yang

We propose a well-posed Maxwell-type boundary condition for the linear moment system in half-space. As a reduction of the Boltzmann equation, the moment equations are available to…

An Approximate Analytical Solution to Knudsen Layers

Ruo Li, Yichen Yang

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 Sha…
