The present paper performs Detached-Eddy Simulations of the actively controlled flow over a 0.35 m chord NACA0015 airfoil at an incidence angle of 11 and. Index Terms-Angle of attack, CFD, NACA 0015, wind tunnel. As result, effect of the stall angle of airfoil performance was investigated. The 15 indicates that the airfoil has a 15 thickness to chord length ratio. Wind tunnel testing is conducted on a NACA0015 airfoil with a rounded trailing edge, known as a circulation control airfoil, at the chord Reynolds number of 1.10×105 and at. In this study, stall angle depended on turbulent occurred behind airfoil was determined. The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The results obtained from experiment and numerical were compared. (e) Coefcient of mean moment about quarter chord, C M. (b) Strouhal number, St, of C L oscillations. The tests involved pitching each aerofoil about its quarter chord point. The experiment test was conducted in low speed wind tunnel, and the numerical analysis was performed using CFD program which was FLUENT. Tani and Nagashima (9) compared the cavitation behavior of a NACA 0015 hydrofoil in water and in cryogenic fluids, showing the important role of the cavity Mach. foil at Re500, compared to the NACA 0015 airfoil from Menon 21. This report summarises the data contained in the Glasgow University dynamic stall database for tests carried out on the NACA 0015, NACA 0018, NACA 0021, NACA 0025 and NACA 0030 aerofoils. Abstract-In the present work, we studied numerical and experimentally analysis lift and drag performances of NACA 0015 airfoil at different attack angle at low Reynolds numbers (Re) by measuring the forces every two degrees from 0° to 20°.
