Simulation of Turbulent Flow around an Airfoil by using κ-ε Model: Angle of Attack Effects

In this paper, unsteady turbulent flow around an airfoil has been studied. Navier-stokes equations solved by Simple C algorithm exerted to specified structured and unstructured grids. Turbulent models used are two-equation κ-e standard model. Equations solved by staggered method and discretization of those done by upwind method. Results show that lift and drag coefficients are increasing functions of the angle of attack.
