The consequence of these coherent structures is a complex time-dependent distrubution of the Nusselt number on the lower wall. Results were computed for water with density variation achieved through temperature differentials. 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.
