Linear Stability of Hyperbolic Moment Models for Boltzmann Equation
Yana Di, Yuwei Fan, Ruo Li +1
Grad's moment models for Boltzmann equation were recently regularized to globally hyperbolic systems, and thus the regularized models attain local well-posedness for Cauchy data. T…
On Hyperbolicity of 13-Moment System
Zhenning Cai, Yuwei Fan, Ruo Li
We point out that the thermodynamic equilibrium is not an interior point of the hyperbolicity region of Grad's 13-moment system. With a compact expansion of the phase density, whic…
Globally Hyperbolic Moment System by Generalized Hermite Expansion
Yuwei Fan, Ruo Li
In a recent paper [Z.-N. Cai, Y.-W. Fan, and R. Li. Tech Report, Institude of Math, Peking Univeristy(2013)], it was revealed that a modified 13-moment system taking intrinsic heat…
Quantum Hydrodynamic Model by Moment Closure of Wigner Equation
Zhenning Cai, Yuwei Fan, Ruo Li +2
In this paper, we derive the quantum hydrodynamics models based on the moment closure of the Wigner equation. The moment expansion adopted is of the Grad type firstly proposed in \…
