The Finite Volume Method (FVM) is a discretization method for the approximation of a single or a system of partial differential equations expressing the conservation, or balance, of one or more quantities. With finite difference methods, conservation is much trickier, and in fact translating a continuous integral (like ∫ρdV) to its discrete equivalent is sometimes itself. Finite volume formulations are natural for systems of conservation laws, and the flux-divergence form makes extension to block-structured adaptive mesh refinement (AMR) easy. The equations that follow all assume that velocity is always positive, and use an upwind (donor-cell) method to get values of thermodynamic variables at volume edges. Nóbrega Download PDF (173 KB).
