Description
This thesis has described a Reynolds Averaged Navier Stokes approach to
modeling turbulence in the wake of a cylinder and airfoil. The mean flow, cross stresses,
and two-point space time correlation structure was analyzed for an untripped cylinder
with a Reynolds number based on the cylinder diameter and freestream velocity of
60,000. The same features were also analyzed using this approach for an untripped
NACA 0012 airfoil with a Reynolds number based on the airfoil chord and freestream
velocity of 328,000. These simulation results were compared to experimental and newly
developed models for validation. The ultimate goal of this present study was to create the
two-point space time correlation function of a cylinder and airfoil wake using RANS
calculations which contributes to a larger study where the sound radiated by an open rotor
due to ingestion of turbulence.
