A compact fourth-order upwind finite-difference scheme for the convection-diffusion equation is developed, by the scheme perturbation technique and the compact second-order upwind scheme. The basic fourth- order scheme, which like the classical upwind scheme is free of cell Reynolds-number limitation in terms of spurious oscillation and involves only immediately neighbouring nodal points, is presented for the one- dimensional equation, and subsequently generalized to multidimensional cases.
