Abstract

Detached-Eddy Simulation proposed by Spalart, Jou, Strelets, and Allmaras, is applied to an axi-symmetric base flow at supersonic conditions. Detached-Eddy Simulation is a hybrid approach to modeling turbulence that combines the best features of the Reynolds-averaged Navier-Stokes and Large Eddy Simulation approaches. In its Reynolds-averaged mode, it is currently based on either the Spalart-Allmaras turbulence model or Menter's Shear Stress Transport model. In its Large Eddy Simulation mode, it is based on the Smagorinski sub-grid scale model. The intended application of Detached- Eddy Simulation is the treatment of massively separated, high-Reynolds number flows over complex configurations (entire aircraft, automobiles, etc.). Because of its intended use for complex configurations, an unstructured grid solver Cobalt is used. The current work incorporates compressible shear layer corrections in both the Spalart-Allmaras based and Shear Stress Transport based DES models. The effect of these corrections on both DES and RANS models is examined. Comparisons are made to the experiments of Herrin and Dutton. Solutions are made on several grids - both structured and unstructured - to test the sensitivity of the models and code to grid refinement and grid type.
