Kurzfassung
This paper presents a method to perform Navier-Stokes computations with the overset grid (or Chimera) approach with grid overlap on body surfaces. The method allows a correct transfer of the flow variables in the boundary layer near curved surfaces. Without the correction the flow is disturbed at the Chimera boundaries. The functionality of the new method is demonstrated for a simple 2D NACA 0012 test case and a more complex 3D helicopter fuselage with wind tunnel support strut. The results for the helicopter configuration are in good agreement with measurements and a computation with a standard multiblock grid.
