On the numerical overshoots of shock‐capturing schemes [PDF]
International Journal for Numerical Methods in Fluids, 2021 AbstractThis note introduces a simple metric for benchmarking shock‐capturing schemes. This metric is especially focused on the shock‐capturing overshoots, which may undermine the robustness of numerical simulations, as well as the reliability of numerical results.

Discontinuity Preserving Scheme [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2020 Non-linear schemes are widely used in high-speed flows to capture the discontinuities present in the solution. Limiters and weighted essentially non-oscillatory schemes (WENO) are the most common non-linear numerical schemes.

MSAT: Matrix stability analysis tool for shock-capturing schemes
SoftwareX, 2023 The simulation of supersonic or hypersonic flows often suffers from numerical shock instabilities if the flow field contains strong shocks, limiting the further application of shock-capturing schemes.

Nonconservative Hybrid Shock Capturing Schemes [PDF]
Journal of Computational Physics, 1992 Hybrid schemes are suggested for a hyperbolic system of conservation laws based on the selection in each node of a difference grid of a suitable approximation of equations via constructed analyzers of the solution smoothness. In the smooth regions, the solution is obtained by easily realized high-order systems based on Runge-Kutta methods with the ...

Shock‐capturing with natural high‐frequency oscillations [PDF]
International Journal for Numerical Methods in Fluids, 2003 AbstractThis paper explores the potential of a newly developed conjugate filter oscillation reduction (CFOR) scheme for shock‐capturing under the influence of natural high‐frequency oscillations. The conjugate low‐ and high‐pass filters are constructed based on the principle of the discrete singular convolution (DSC), a local spectral method.
