An efficient high-order gas-kinetic scheme with hybrid WENO-AO method for the Euler and Navier-Stokes solutions

, 2023
The high-order gas-kinetic scheme (HGKS) features good robustness, high efficiency and satisfactory accuracy,the performaence of which can be further improved combined with WENO-AO (WENO with adaptive order) scheme for reconstruction.

Review on non-polynomial high-order accuracy nonlinear weighted schemes

Kongqi donglixue xuebao
In comparison to linear schemes, the nonlinear errors inherent in polynomial-based high-order nonlinear weighted schemes significantly affect the resolution when solving weak solutions of hyperbolic conservation laws. To mitigate this impact, researchers

A Class of Finite Difference Schemes with Adaptive Controllable Dispersion and Low Dissipation for Compressible Turbulence

Fluids
The dispersion and dissipation properties of a numerical scheme are critical in simulating flow fields involving a wide range of length scales. In this study, we highlight the common oversight of focusing merely on controlling dispersion error without ...

A high-resolution WENO scheme with multiple global smoothness indicators in compressible fluids

Results in Applied Mathematics
A novel fifth-order WENO-Z-type scheme with multiple global smoothness indicators (MGSI-WENO-Z) is proposed for compressible multi-scale flows. Unlike conventional WENO-Z schemes with a single global smoothness indicator, distinct GSIs are assigned to ...

Accuracy of MUSCL and WENO Schemes on Non-Uniform Structured Meshes

气体物理
The difference schemes constructed on the basis of one-dimensional uniform grids must be extended to non-uniform or curvilinear grids in practical applications, and the coordinate transformation process introduces geometry-induced errors. The accuracy of

High-order weno-θ6 finite volume method for two-dimensional compressible euler equations

Tạp chí Khoa học và Công nghệ
A high-order finite-volume WENO-θ6 method is proposed for two-dimensional compressible Euler equations. The method employs θ-adaptive weighting to combine fifth-order upwind and sixth-order central reconstructions based on local smoothness indicators ...

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

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
