Resumo
Concern about environmental imbalances is frequent throughout the world and
investment in clean and renewable energy is increasing progressively. The assessment of
wind resources becomes increasingly challenging, as it takes into account environmental
parameters, such as climate fluctuations, in addition to financial expenses in feasibility
studies for the construction of wind farms. For these studies, the estimation of wind
potential uses numerical and experimental models as a complement to field
measurements. This work refers to the experimental study in a wind tunnel made,
available by FURNAS of the atmospheric boundary layer variation from an apparatus
known as a flat boundary layer plate, which contains installed pressure probes and a flap
mechanism installed on the trailing edge. Different combinations of angles (-10°, +10°,
0°, -20°, +20°) and velocities (6, 13, 20, 26 and 33 m.s-1
) were made. The results obtained
show that, when modifying the flap positioning angle, the boundary layer generated on
the plate undergoes significant changes. When analyzing the angle separately for each
speed, the boundary layer generated is significantly different for all speeds studied. The
wind potential was better at high speeds and had a slight increase at negative flap angles.
