Variation of the Forces with the Wind Direction to an Experimental Model of Aerodynamic Profile of Wind Turbine
Keywords:
wind tunnel, lift force, drag force
Abstract
The work is based on wind tunnel experiments on an experimental turbine blade model. The vertical force (Lift) and the resisting force (Drag, in the wind direction) are measured. The tests can be considered under static conditions because the experimental model rotates with a hexadecimal degree per second. The measurement range is 180 (-90...+90) at the maximum wind speed of 9 m/s. The results confirm the importance of the position of the blade with respect to the wind direction and its speed.
