A favourable/adverse-pressure-gradient boundary layer flow is computed with the zonal grid approach applied to direct numerical simulation (DNS). The computational domain covers a big part of Watmuff’s experimental flow domain [15]. Experimental and DNS results are compared with statistical calculations by a boundary layer code, using the к - ω model and Menter’s SST model [10]. The streamwise development of global quantities are shown as well as the mean streamwise velocity component, Reynolds shear stress and turbulent kinetic energy. Boundary layer calculations with turbulence models are in fair agreement with the DNS data and the experiment. Nevertheless, the prediction of the Reynolds shear stress and the turbulent kinetic energy could be improved.
