A hybrid kinetic WENO scheme for inviscid and viscous flows

open access: yes, 2015
In this paper, we propose a high-order finite volume hybrid kinetic Weighted Essentially Non-Oscillatory (WENO) scheme for inviscid and viscous flows.

Several Models for Verificating Numerical Solution of Euler Equation

open access: yes气体物理
The authors have successively found numerical examples in which the computational error of the WENO is larger than that of the first-order upwinding scheme under specific conditions since 2018.

An efficient third-order WENO scheme with unconditionally optimal accuracy [PDF]

open access: yes
A novel scheme, based on third-order Weighted Essentially Non-Oscillatory (WENO) reconstructions, is presented. It attains unconditionally optimal accuracy when the data is smooth enough, even in presence of critical points, and second-order ccuracy if a

A New WENO‐Based Momentum Advection Scheme for Simulations of Ocean Mesoscale Turbulence

open access: yesJournal of Advances in Modeling Earth Systems
Current eddy‐permitting and eddy‐resolving ocean models require dissipation to prevent a spurious accumulation of enstrophy at the grid scale. We introduce a new numerical scheme for momentum advection in large‐scale ocean models that involves upwinding ...

KFVM-WENO: A High-order Accurate Kernel-based Finite Volume Method for Compressible Hydrodynamics

open access: yesThe Astrophysical Journal
This paper presents a fully multidimensional kernel-based reconstruction scheme for finite volume methods applied to systems of hyperbolic conservation laws, with a particular emphasis on the compressible Euler equations. Nonoscillatory reconstruction is
