WebIn this work we propose a novel strategy to define high-order fully well-balanced Lagrange-projection finite volume solvers for balance laws. In particular, we focus on the 1D shallow water system as it is a reference system of balance laws with non-trivial stationary solutions. Nevertheless, the strategy proposed here could be extended to other interesting … WebThis method of deriving the discrete equation using Taylor’s series expansions is called the finite-difference method. However, most commercial CFD codes use the finite-volume or finite-element methods which are better suited for …

High-Order Finite Volume Methods for Aerosol Dynamic Equations
WebFeb 14, 2024 · 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 Squares approximations in order to obtain higher-order accurate reconstruction and connectivity between the overlapped grids. WebA cell-centered multipoint flux approximation method with a diamond stencil coupled with a higher order finite volume method for the simulation of oil–water displacements in heterogeneous and anisotropic petroleum reservoirs. Computers & Fluids, Vol. 127. WebFirst we have presented an arbitrary high-order Finite Volume scheme based on convex combi-nations of the standard first-order Godunov scheme and on a separated treatment of the space and time discretizations. It is simple to implement in an existing first-order code and that ex-plains our motivation to choose it in the context of this thesis. sickness going around 2020
