Abstract

A systematic comparison of several differencing schemes for the convection terms in high Reynolds number elliptic flow has been conducted. The schemes considered here are first-order upwinding, skew upwind differencing, second-order upwinding, second-order central differencing, and QUICK. The test cases were one- and two-dimensional model problems, laminar driven-cavity flows, and flows in complex geometries. Their performances in both Cartesian and body-fitted coordinates are considered, with emphasis on the different strengths of the different schemes. For steady-state high Reynolds number complex flow calculations, the second-order upwind scheme appears to be the best choice. In addition, the authors study the effects of the interaction between numerical schemes and grid distribution on numerical accuracy and stability.
