The details of how a vortex lifts off a blunt swept leading edge are not so well understood, and this paper undertakes a comprehensive CFD study of the phenomena. Current day experience shows that the location for the start of the vortex depends on the grid resolution of the numerical solution and the physical modeling used to account for the turbulence in the flow. In this work multiple levels of grid refinement, together with ap- propriate adaptation of the grids, are carried out to the extent that stabilizes the location of the separation. Various turbulence models are also used in combination with the grid sequencing showing a strong effect on vortex separation position due to chosen turbulence model.
