Our aim is to get basic data to increase the efficiency of micro horizontal axis wind turbine (HAWT)systems. The experiments were carried out in an open type wind tunnel and on field. We measured theturbine performance of five-bladed wind turbines with Clark Y, MEL002 and MEL081 airfoil crosssections.Flow characteristics of rotating blades of the turbine were observed using the oil-film and tuftvisualization technique. Flow visualization allowed the identification of laminar flow, laminar separationbubble formation, flow reattachment, turbulent boundary layer, and turbulent separation. The complexpatterns on the rotating blade surface were confirmed and identified by the oil-film visualizationmethod. The performance of the wind turbine with MEL081 airfoil section was better than the otherairfoil sections at low wind speed. It was found that the performance of wind turbine with trip-tapes,which were employed for control of the blade boundary layer, improved at low wind speed.
