Numerical Simulation of the Aerodynamic Characteristics of NACA0012 Airfoil Based on Operational Parameters

This study investigated the performance of symmetric airfoils type NACA0012 numerically under different operating conditions. It has been assumed that involves steady state, non-compressive, and turbulent flows. The fluid was air. effect Reynolds number angle attack on lift drag coefficients, pressure distribution, velocity distribution investigated. ANSYS FLUENT used to solve numerical model by using continuity equations, Navier-Stokes appropriate K-ω SST perturbation model. shows a clear difference between coefficient lower upper surfaces airfoil at high numbers, indicating higher numbers. As maximum stall is 14° after which it decreases significantly, direct relationship observed coefficients attack.
