Development of a Wall Treatment for Navier-Stokes Computations using the Overset-Grid Technique

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