-tensor gradient flow with quasi-entropy and discretizations preserving physical constraints
Yanli Wang, Jie Xu
We propose and analyze numerical schemes for the gradient flow of -tensor with the quasi-entropy. The quasi-entropy is a strictly convex, rotationally invariant elementary funct…
Learning invariance preserving moment closure model for Boltzmann-BGK equation
Zhengyi Li, Bin Dong, Yanli Wang
As one of the main governing equations in kinetic theory, the Boltzmann equation is widely utilized in aerospace, microscopic flow, etc. Its high-resolution simulation is crucial i…
Numerical Solver for the Boltzmann Equation With Self-Adaptive Collision Operators
Zhenning Cai, Yanli Wang
We use the Burnett spectral method to solve the Boltzmann equation whose collision term is modeled by separate treatments for the low-frequency part and high-frequency part of the…
An asymptotic-preserving IMEX method for nonlinear radiative transfer equation
Weiming Li, Peng Song, Yanli Wang
We present an asymptotic preserving method for the radiative transfer equations in the framework of PN method. An implicit and explicit method is proposed to solve the P N system b…
A Robust Riemann Solver for Multiple Hydro-Elastoplastic Solid Mediums
Ruo Li, Yanli Wang, Chengbao Yao
We propose a robust approximate solver for the hydro-elastoplastic solid material, a general constitutive law extensively applied in explosion and high speed impact dynamics, and p…
Approximation to Singular Quadratic Collision Model in Fokker-Planck-Landau Equation
Ruo Li, Yanli Wang, Yixuan Wang
We propose a Hermite-Galerkin spectral method to numerically solve the spatially homogeneous Fokker-Planck-Landau equation with singular quadratic collision model. To compute the c…
