Over the last ten years, robustness of schemes has raised an increasing interest among the CFD community. One mathematical aspect of scheme robustness is the positivity preserving property. At high Mach numbers, solving the conservative Euler equations can lead to negative densities or internal ener

In the present work, a recently proposed flux-splitting scheme suitable for compressible flow is extended to incompressible flows. Appropriate dissipation terms for both incompressible and compressible flows are determined by expanding the Roe flux-difference splitting in terms of Mach number. Analy
A geometrically conservative one-dimensional (1D) arbitrary Lagrangian-Eulerian (ALE) version of the advective upstream splitting method (AUSM) shock capturing scheme is presented. The spatial discretization is based on a modified form of AUSM which splits the flux vector according to the eigenvalue
In this paper we deal with the construction of hybrid flux-vector-splitting (FVS) schemes and flux-difference-splitting (FDS) schemes for a two-phase model for onedimensional flow. The model consists of two mass conservation equations (one for each phase) and a common momentum equation. The complexi
In this paper we focus our attention on obtaining well-balanced schemes for balance laws by using MarquinaΓs flux in combination with the finite difference and finite volume WENO schemes. We consider also the Rusanov flux splitting and the HLL approximate Riemann solver. In particular, for the prese
