The RANS code Fluent TM 6.1 is used to predict the flow field around a pitching NACA 0012 airfoil. A hybrid mesh was employed in the computational domain and different mesh configurations are tested and the results are compared. Twoequation turbulence models namely k-є, r k- є, k-ω, and SST k-ω were tested and their results are compared. The turbulence model that gives the best agreement with the experimental data for 2D case is SST k-ω with y+ value set to 1. Mesh and time step dependency… Expand
