N2 - Capability of recently developed Menter (ME) and Modified Menter (MME) one-equation models in predicting prestall and poststall characteristics of three airfoils that exhibit different stall onset mechanisms is investigated. The Spalart-Allmaras (SA) turbulence model is also included to form a baseline against which both the ME and the MME models are assessed. The effects of subiteration, grid size, and time stepping on the predictive accuracy of the numerical scheme are addressed. However, transition effect is not accounted for and hence, all test cases are run fully turbulent. Significant differences in the flow predictions of all models are noticed in regions with massively flow separation.
