Resumo: The Computational Fluid Dynamics is extensively employed in aerospace industry, which has become feasible due to the evolution of the computers (increased capacity) and to the relatively low computational cost. A great challenge is the inclusion of viscosity effects in the flow simulations, also using a mesh fine enough to catch all the velocity fluctuations due to turbulence. The demand for computational power makes it unfeasible for aerospace applications. Due to the coming of the turbulence models and Reynolds-averaged Navier-Stokes equations, the use of CFD has become common in aerospace industry, allowing optimization and reducing cycles of wind tunnel testing. This work presents the results of two-dimensional flow simulations made using three different turbulence models, as well as two distinct airfoils - a conventional and a supercritical. The simulated cases were chosen taking into account the availability of data for validation. A discussion concerning the results is presented, as well as the conclusion.
