## Abstract A higher‐order accurate numerical scheme is developed to solve the two‐dimensional advection–diffusion equation in a staggered‐grid system. The first‐order spatial derivatives are approximated by the fourth‐order accurate finite‐difference scheme, thus all truncation errors are kept to

High-order-accurate methods for viscous flow problems have the potential to reduce the computational effort required for a given level of solution accuracy. The state of the art in this area is more advanced for structured mesh methods and finiteelement methods than for unstructured mesh finite-volu
An artificial-viscosity finite-difference scheme is introduced for stabilizing the solutions of advectiondiffusion equations. Although only the linear one-dimensional case is discussed, the method is easily susceptible to generalization. Some theory and comparisons with other well-known schemes are
