Predictions are presented of the two-dimensional turbulent flow around a hill; the two-dimensional Reynolds equations are written in an orthogonal curvilinear coordinate system and transformed to finite difference form after discretisation in physical space. Turbulence is simulated by the κ−ϵ model of turbulence; the first part of the paper compares predictions with available laboratory data; in the second part the results of the developed method are compared with results of other numerical methods; therefore, the validity of the method, its flexibility to treat any hill shape and its reliability compared to other methods is assessed.
