Assessment of a high-order shock-capturing central-difference scheme for hypersonic turbulent flow simulations [PDF]

open access: yes, 2021
High-speed turbulent flows are encountered in most space-related applications (including exploration, tourism and defense fields) and represent a subject of growing interest in the last decades.

A high order compact scheme for hypersonic aerothermodynamics [PDF]

open access: yes, 2010
A novel high order compact scheme for solving the compressible Navier-Stokes equations has been developed. The scheme is an extension of a method originally proposed for solving the Euler equations, and combines several techniques for the solution of ...

Discontinuity Preserving Scheme [PDF]

open access: yesInternational 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.

Shock‐capturing with natural high‐frequency oscillations [PDF]

open access: yesInternational 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.

MSAT: Matrix stability analysis tool for shock-capturing schemes

open access: yesSoftwareX, 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.

A shock-capturing meshless method for solving the one-dimensional Saint-Venant equations on a highly variable topography

open access: yesJournal of Hydroinformatics, 2023
The Saint-Venant equations are numerically solved to simulate free surface flows in one dimension. A Riemann solver is needed to compute the numerical flux for capturing shocks and flow discontinuities occurring in flow situations such as hydraulic jump,

The Role of Mesh Generation, Adaptation, and Refinement on the Computation of Flows Featuring Strong Shocks

open access: yesModelling and Simulation in Engineering, 2012
Within a continuum framework, flows featuring shock waves can be modelled by means of either shock capturing or shock fitting. Shock-capturing codes are algorithmically simple, but are plagued by a number of numerical troubles, particularly evident when ...

Improving the quantification of overshooting shock-capturing oscillations [PDF]

open access: yes, 2023
An approach for quantitatively evaluating overshooting oscillations is designed to characterize the performance of shock-capturing schemes. Specifically, following our previous work focused on cases with only discontinuities, now we account for the ...
