Abstract: Highlights: [•] Major features of unsteady flow are identified from DNS results. [•] Performance of turbulence models are assessed against these features. [•] Launder and Sharma (1974) [36] and Langtry and Menter’s (2009) transition SST are best models. [•] Chang et al. (1995) [28] is also good but can be unstable sometimes. [Copyright &y& Elsevier]
