摘要

The relative performances of five pressure-velocity coupling solution algorithms, SIMPLE, CTS SIMPLE, SIMPLER. SIMPLEC and FIMOSE, are evaluated for three turbulent flow problems. The characteristics of these methods are investigated based on the computational effort required to reach certain levels of residuals in mass, momentum and turbulent kinetic energy. Comparisons of these methods used to solve turbulent flows in the present study and laminar calculations in previous literature are made to reveal the characteristic behaviour of these algorithms in the computation of these two flow regimes. It is found that SIMPLEC is the most efficient and stable method for solving the complex turbulent flows and its performance is not always identical to CTS SIMPLE. SIMPLER needs the fewest iterations.
