An attempt was made to show that a combination of an upwind thin-layer Navier-Stokes solver with the Johhson-King half-equation algebraic turbulence model offers consistently better results than the standard baseline models, including zero-, one or two equation models. In the present study, in order to improve the robustness, certain compromises have been done on the half-equation model without degrading the accuracy. Implementation has been concentrated on the ONERA M6 wing. Present results demonstrate that the new model performs significantly better on one transonic separated wing flow case than the baseline and other more complicated higher order eddy-viscosity models.
