Skew-Symmetric Formulations and Energy-Stable Schemes for Compressible Reactive Flow Equations
Junbo Gong, Weifeng Zhao
This paper develops skew-symmetric formulations and energy stable finite difference schemes for the reactive Euler and reactive Navier--Stokes equations. By introducing suitable tr…
Validity of relaxation models arising from numerical schemes for hyperbolic-parabolic systems
Zhiting Ma, Weifeng Zhao
This work is concerned with relaxation models arising from numerical schemes for hyperbolic-parabolic systems. Such models are a hyperbolic system with both the hyperbolic part and…
Boundary treatment of high order Runge-Kutta methods for hyperbolic conservation laws
Weifeng Zhao, Juntao Huang, Steven J. Ruuth
In \cite{ZH2019}, we developed a boundary treatment method for implicit-explicit (IMEX) Runge-Kutta (RK) methods for solving hyperbolic systems with source terms. Since IMEX RK met…
Boundary treatment of implicit-explicit Runge-Kutta method for hyperbolic systems with source terms
Weifeng Zhao, Juntao Huang
In this paper, we develop a high order finite difference boundary treatment method for the implicit-explicit (IMEX) Runge-Kutta (RK) schemes solving hyperbolic systems with possibl…
Relaxation-rate formula for the entropic lattice Boltzmann method
Weifeng Zhao, Wen-An Yong
An elegant and uniform relaxation-rate formula is presented for the entropic lattice Boltzmann method (ELBM). The formula not only guarantees the discrete time H-theorem at numeric…
A family of single-node second-order boundary schemes for the lattice Boltzmann method
Weifeng Zhao, Wen-An Yong
In this work, we propose a family of single-node second-order boundary schemes for the lattice Boltzmann method with general collision terms. The construction of the schemes is qui…
