“…Furthermore, with the continuing development of high-performance aircraft and helicopters, dynamic stall and blade stall flutter have been of increasing concern. A few other examples are the flows generated by devices such as turbo machines and wind turbine blades, which have received considerable attentions in recent years (4)(5)(6)(7) . The study of the aerodynamics of wind turbines began after world war .…”

“…These are inclusive of considerations for the size of roughness, flow turbulence, dynamic stall, etc. (7,8) To the authors' knowledge, there is no experimental/computational information regarding the pressure distribution and the boundary-layer transition on this aerofoil at either steady or unsteady conditions. Therefore, it was decided to measure the above variables at different flow conditions.…”

Extensive experiments were conducted to study the effect of various parameters on the surface pressure distribution and transition point of an aerofoil section used in a wind turbine blade. In this paper details of the variation of transition point on the aforementioned aerofoil are presented. The aerofoil spanned the wind-tunnel test section and was oscillated sinusoidally in pitch about the quarter chord. The imposed variables of the experiments were free stream velocity, amplitude of motion, mean angle-of-attack, and oscillation frequency. The spatial-temporal progressions of the leading-edge transition point and the state of the unsteady boundary-layer were measured using eight closely-spaced, hot-film sensors (HFS). The measurements show that: (i) Reduced frequency has a pronounced effect on the variations of the transition point. (ii) There exists a hysteresis loop in the dynamic transition location and its shape varies with the reduced frequency and mean angle-of-attack.
