WENO Scheme Based on Lax-Wendroff Time Discretization to Solving Hyperbolic Conservation Laws

open access: yesJournal of Harbin University of Science and Technology, 2017
The research of high accuracy and high resolution schemes have been a hot topic in computational mathematics. According to low resolution and large amount of calculation of the original WENO-JS scheme,we propose a simple new limiter fifth order upwind ...

New Constructing Method for WENO Schemes

open access: yesProcedia Engineering, 2013
AbstractA new method for constructing weighted essentially non-oscillatory (WENO) scheme is proposed. The idea of this method is to combine Henrick's mapping function and the idea of improving the accuracy of WENO-Z scheme one-by-one order. The particular advantage of the new constructing method is that it can improve the accuracy of WENO scheme near ...

Tensor-train WENO scheme for compressible flows [PDF]

open access: yesJournal of Computational Physics
In this study, we introduce a tensor-train (TT) finite difference WENO method for solving compressible Euler equations. In a step-by-step manner, the tensorization of the governing equations is demonstrated. We also introduce \emph{LF-cross} and \emph{WENO-cross} methods to compute numerical fluxes and the WENO reconstruction using the cross ...

Application of High-Order WENO Scheme in the CFD/FW–H Method to Predict Helicopter Rotor Blade–Vortex Interaction Tonal Noise

open access: yesAerospace, 2022
The accurate prediction of helicopter rotor blade–vortex interaction (BVI) noise is challenging. This paper presents an implementation of the seventh-order improved weighted essentially non-oscillatory (WENO-Z) scheme for predicting rotor BVI noise using

Convergence of a proposed adaptive WENO scheme for Hamilton-Jacobi equations [PDF]

open access: yes, 2023
summary:We study high-order numerical methods for solving Hamilton-Jacobi equations. Firstly, by introducing new clear concise nonlinear weights and improving their convex combination, we develop WENO schemes of Zhu and Qiu (2017).

A New Mapped WENO Method for Hyperbolic Problems

open access: yesAerospace, 2022
In this study, a new family of rational mapping functions gRM(ω;k,m,s) is introduced for seventh-order WENO schemes. gRM is a more general family of mapping functions, which includes other mapping functions such as gM and gIM as special cases. The mapped
