A Two-Step High-Order Compact Corrected WENO Scheme

Algorithms
In this study, we introduce a novel 2-step compact scheme-based high-order correction method for computational fluid dynamics (CFD). Unlike traditional single-formula-based schemes, our proposed approach refines flux function values by leveraging results

Compact-Corrected MUSCL: A Flexible, Low-Cost High-Accuracy Scheme for High-Speed Flow Simulation

Algorithms
High-order numerical methods are essential for achieving predictive fidelity in modern computational fluid dynamics, yet many existing schemes face significant trade-offs between accuracy, robustness, and computational efficiency.

Multi-step Weighted Essentially Non-oscillatory Scheme

, 2013
A fifth-order accurate multi-step weighted essentially non-oscillatory (WENO) scheme is constructed in this paper. Different from the traditional WENO schemes, which are designed to have ( 2 r 1 )th order accuracy in the smooth regions directly from r ...

Comparison of fifth-order weno scheme and finite volume weno-gas-kinetic scheme for inviscid and viscous flow simulation

, 2013
The development of high-order schemes has been mostly concentrated on the limiters and high-order reconstruction techniques. In this paper, the effect of the flux functions on the performance of high-order schemes will be studied.
