Hermite spectral method for the inelastic Boltzmann equation
Ruo Li, Yixiao Lu, Yanli Wang
We propose a Hermite spectral method for the inelastic Boltzmann equation, which makes two-dimensional periodic problem computation affordable by the hardware nowadays. The new alg…
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…
Coupling conditions for linear hyperbolic relaxation systems in two-scales problems
Juntao Huang, Ruo Li, Yizhou Zhou
This work is concerned with coupling conditions for linear hyperbolic relaxation systems with multiple relaxation times. In the region with small relaxation time, an equilibrium sy…
Hermite spectral method for multi-species Boltzmann equation
Ruo Li, Yixiao Lu, Yanli Wang +1
We introduce a numerical scheme for the full multi-species Boltzmann equation based on Hermite spectral method. With the proper choice of expansion centers for different species, a…
Direct Flux Gradient Approximation to Close Moment Model for Kinetic Equations
Ruo Li, Weiming Li, Lingchao Zheng
To close the moment model deduced from kinetic equations, the canonical approach is to provide an approximation to the flux function not able to be depicted by the moments in the r…
Hyperbolic Model Reduction for Kinetic Equations
Zhenning Cai, Yuwei Fan, Ruo Li
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 hyperbol…
