Parity-decomposition and Moment Analysis for Stationary Wigner Equation with Inflow Boundary Conditions
Ruo Li, Tiao Lu, Zhangpeng Sun
We study the stationary Wigner equation on a bounded, one-dimensional spatial domain with inflow boundary conditions by using the parity decomposition in (Barletti and weifel, Tran…
Acceleration for Microflow Simulations of High-Order Moment Models by Using Lower-Order Model Correction
Zhicheng Hu, Ruo Li, Zhonghua Qiao
We study the acceleration of steady-state computation for microflow, which is modeled by the high-order moment models derived recently from the steady-state Boltzmann equation with…
13-Moment System with Global Hyperbolicity for Quantum Gas
Yana Di, Yuwei Fan, Ruo Li
We point out that the quantum Grad's 13-moment system [R. Yano, Physica A: Statistical Mechanics and its Applications, 416:231-241, 2014] is lack of global hyperbolicity, and even…
Preserving Hyperbolicity in Stochastic Galerkin Method for Uncertainty Quantification
Zhenning Cai, Ruo Li, Yanli Wang
We first investigate the structure of the systems derived from the gPC based stochastic Galerkin method for the nonlinear hyperbolic systems with random inputs. This method adopts…
