摘要：Low Reynolds number k-Ε models are applicable in the whole range from fully turbulent flow zone to the walls; their applicable range is wider than the standard k-Ε model. In this paper, three turbulent flows with benchmark experimental data were selected for validation and comparison between five low Reynolds number k-Ε models. The standard k-Ε model was also included for comparison. The numerical results showed that in these models, the NH model was able to obtain better agreements with experiments than other four low Reynolds models. The standard k-Ε model, however, obtained worse agreement for separated flows at less computational costs, as compared with low Reynolds k-Ε models.
