Descrição: dc.descriptionComputational Fluid Dynamics (CFD) techniques are currently an alternative or complementary approach to experimental tests in the field of fluid dynamics. Therefore, this article aims to numerically study the airflow around the NACA 0012 airfoil profile at low speeds using ANSYS® Fluent and two turbulence models (Spalart Allmaras and k-ε). The objective is to evaluate the coefficients of lift, drag, and pressure, as well as the lift to-drag ratio and turbulent wake distribution. The results were considered acceptable through experimental research by Abbott, et al. [1] and Ladson, et al. [2] and showed promising results (CL with an error margin below 5% and maximum aerodynamic efficiency L/D at α = 9°), although they are physically coherent but not as precise (CD demonstrated an error margin of 50%). It was also observed that the Spalart-Allmaras model exhibited better physical coherence in the turbulent wake distribution results compared to the k-ε model, indicating that the latter is not recommended for simulations subjected to adverse pressure gradients.-
