The primary difference is that they have employed 32 turning vanes while we have used 16. Approximately 1 million grid points distributed over 84 blocks are used in the simulation. The algebraic Reynolds stress model of Gatski and Speziale was employed. Contours represent levels of constant vorticity magnitude . Isosurfaces of constant pressure .
Colors represent levels of vorticity magnitude .
Development and Evolution of a Tip Vortex in the Near Field Tip Vortex formation over a NACA 0015 airfoil with a flat end-cap at Reynolds number of 1.5 million. The algebraic turbulence model of Gatski and Speziale was employed. Colors coded to levels of constant vorticity magnitude. A C-O grid with 277x75x79 grid points was used.
