A Class of Upwind Finite Volume Schemes for One-Dimensional Steady Convection-Dominated Diffusion Equations
摘要
Abstract
In this paper, a class of upwind finite volume scheme is presented for one dimensional steady convection-dominated diffusion equations. The scheme has second order accuracy for convective term and first order accuracy for diffusive term, which completely coincides with the character of strong convection and weak diffusion for convection-dominated diffusion problems.关键词
