WebThe Finite volume method in computational fluid dynamics is a discretization technique for partial differential equations that arise from physical conservation laws. These equations can be different in nature, e.g. elliptic, parabolic, or hyperbolic.The first well-documented use of this method was by Evans and Harlow (1957) at Los Alamos. Web16 hours ago · Abstract. We present a novel discretization for the two-dimensional incompressible Magnetohydrodynamics (MHD) system coupling an electromagnetic model and a fluid flow model. Our approach follows the framework of the Virtual Element Method and offers two main advantages. The method can be implemented on unstructured … WebIn this video, I'll explain the discretization approach to 2D convection-diffusion system using finite volume method.
