Application of Navier-Stokes Code Pab3d with kappa-Epsilon Turbulence Model toAttached and Separated Flows

摘要

A three-dimensional Navier-Stokes solver was used to determine how accuratelycomputations can predict local and average skin friction coefficients for attached and separated flows for simple experimental geometries. Algebraic and transport equation closures were used to model turbulence. To simulate anisotropic turbulence, the standard two-equation turbulence model was modified by adding nonlinear terms. The effects of both grid density and the turbulence model on the computed flow fields were also investigated and compared with available experimental data for subsonic and supersonic free-stream conditions.
