| Abstract | Compact second-order upwind finite difference schemes, which are free of cell Reynolds number limitation, were developed in this paper for 1D to 3D steady convection diffusion equations, using a perturbational technique applied to classical first-order upwind schemes. The present second-order schemes take essentially the same form as those of the first-order schemes, but involve a simple modification for the diffusive coefficients. Numerical examples including 1D to 3D model equations of fluid flow and a problem of natural convection with boundary-layer effect were given to illustrate the excellent behavior of the present schemes. |
