Solving Vlasov Equations Using NRxx Method
Zhenning Cai, Ruo Li, Yanli Wang
In this paper, we propose a moment method to numerically solve the Vlasov equations using the framework of the NRxx method developed in [6, 8, 7] for the Boltzmann equation. Due to…
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 \…
Globally Hyperbolic Regularization of Grad's Moment System
Zhenning Cai, Yuwei Fan, Ruo Li
In this paper, we propose a globally hyperbolic regularization to the general Grad's moment system in multi-dimensional spaces. Systems with moments up to an arbitrary order are st…
The NRxx Method for Polyatomic Gases
Zhenning Cai, Ruo Li
In this paper, we propose a numerical regularized moment method to solve the Boltzmann equation with ES-BGK collision term to simulate polyatomic gas flows. This method is an exten…
