The main objective of this study is to assess the performance of RANS models in simulating a complex flow field around an aerofoil with high-lift devices. Three low-Reynolds-number (LRN) RANS models were tested, i.e., a conventional linear LRN k-ε model, a linear k-ω model, and an advanced no-linear LRN k-ω model recently developed. The computed results were compared with those by the corresponding experiment, including drag, lift, and total pressure coefficients. The examined conventional linear k-ε and k-ω models showed similar trends and gave poor performance. On the other hand, the advanced non-linear k-ω model returned much better results than the other two models did. Considerable differences were seen between the conventional linear RANS models and the advanced non-linear model presently examined.
