Numerical diffusion impairs the accuracy of discrete solutions of the equations governing the convective transport of a scalar when the flow is not aligned with grid lines. Numerical diffusion leads to unintentional smoothing of advected gradients. This work presents an assessment of numerical diffusion in CFD code FLUENT 6.3 and available means of reducing impairment.
