We also analyzed the impact of the vortex structure on the fled flow around the wing and the spectral characteristics corresponding to the vortex. The dominant frequency and harmonic frequency corresponding to the wave rule of the shedding vortex at various attack angles witho...
The transitional flow past a NACA0012 airfoil at Reynolds numbers, Re, between 50,000 and 140,000 is investigated using experiments and low and high-fidelity numerical simulations. Variations in Reynolds number provide the quasi-steady response of the flow and resulting lift to dynamic inflow (var...
The NACA airfoil series, developed by the NACA in the early 20th century, has been due to its well-defined aerodynamic characteristics. The NACA 0012 airfoil, in particular, is known for its symmetrical shape and has been used in a wide range of applications, including general aviation ...
