Recasting an operator splitting solver into a standard finite volume flux-based algorithm. The case of a Lagrange-Projection-type method for gas dynamics
Rémi Bourgeois, Pascal Tremblin, Samuel Kokh +1
In this paper, we propose a modification of an acoustic-transport operator splitting Lagrange-projection method for simulating compressible flows with gravity. The original method…
An all-regime and well-balanced Lagrange-projection type scheme for the shallow water equations on unstructured meshes
Christophe Chalons, Samuel Kokh, Maxime Stauffert
In this work, we focus on the numerical approximation of the shallow water equations in two space dimensions. Our aim is to propose a well-balanced, all-regime and positive scheme.…
Experimenting with the p4est library for AMR simulations of two-phase flows
Florence Drui, Alexandru Fikl, Pierre Kestener +4
Many physical problems involve spatial and temporal inhomogeneities that require a very fine discretization in order to be accurately simulated. Using an adaptive mesh, a high leve…
Sharpening methods for finite volume schemes
B Després, S Kokh, Frédéric Lagoutière
We review sharpening methods for finite volume schemes, with an emphasis on the basic structure of sharpening methods. It covers high order methods and non linear techniques for li…
A large time-step and well-balanced Lagrange-Projection type scheme for the shallow-water equations
Christophe Chalons, Pierre Kestener, Samuel Kokh +1
This work focuses on the numerical approximation of the Shallow Water Equations (SWE) using a Lagrange-Projection type approach. We propose to extend to this context recent implici…
Simulation of sharp interface multi-material flows involving an arbitrary number of components through an extended five-equation model
Marie Billaud Friess, Samuel Kokh
In this paper, we present an anti-diffusive method dedicated to the simulation of interface flows on Cartesian grids involving an arbitrary number m of compress- ible components. O…
