Abstract
In recent years, three higher-order non-oscillatory schemes, SMART, SHARP and HLPA, have been proposed for the simulation of steady incompressible flows. This paper presents a comparison of these schemes in terms of their numerical accuracy, computational cost and algorithmic simplicity. The comparison is made on the basis of applications to three test problems, one linear and two non-linear, all involving a simultaneous presence of convective dominance and flow-to-grid skewness. Computed results show that the three schemes yield similar solutions which are nearly as good as those obtained with the QUICK scheme but without the physically unrealistic oscillations of the latter. However, there is a marked variation in their computational costs, especially in the case of fine grids.
