Very high-order method on immersed curved domains for finite difference schemes with regular Cartesian grids
(Elsevier, 2020)[Abstract:] A new very high-order technique for solving conservation laws with curved boundary domains is proposed. A Finite Difference scheme on Cartesian grids is coupled with an original ghost cell method that provide ... -
An a posteriori, efficient, high-spectral resolution hybrid finite-difference method for compressible flows
(Elsevier, 2018)[Abstract:] A high-order hybrid method consisting of a high-accurate explicit finite-difference scheme and a Weighted Essentially Non-Oscillatory (WENO) scheme is proposed in this article. Following this premise, two ... -
A Higher‑Order Chimera Method for Finite Volume Schemes
(Springer, 2018)[Abstract:] In this work a higher-order accurate finite volume method for the resolution of the Euler/Navier–Stokes equations using Chimera grid techniques is presented. The formulation is based on the use of Moving Least ... -
A reduced-dissipation WENO scheme with automatic dissipation adjustment
(Elsevier, 2020)[Abstract:] In this paper, we propose a novel modification to the WENO-family schemes to reduce its intrinsic dissipation. In this work, we focus on the WENO5 scheme, which is rewritten in terms of a central plus a dissipative ... -
A high-order finite volume method with improved isotherms reconstruction for the computation of multiphase flows using the Navier–Stokes–Korteweg equations
(Elsevier, 2020)[Abstract] In this work we solve the Navier–Stokes–Korteweg (NSK) equations to simulate a two-phase fluid with phase change. We use these equations on a diffuse interface approach, where the properties of the fluid vary ...
