Abstract
The installed capacity of wind energy around the
world using big horizontal-axis wind turbines (HAWT) has grown
substantially in the last two decades. Likewise, research and
development of vertical-axis wind turbines (VAWT) for small
power applications has been increased during the last seven years.
This paper presents the performance analysis related to the power
output of a micro VAWT with three blades in helicoidal form,
based on computacional fluids dynamics simulation (CFD), using
Ansys Fluentr. In the analysis, several parameters related to
the aerodynamic performance were varied, keeping constant the
sweeping area. To compare results, a mathematical model was
created in Matlabr, using the double-multiple streamtube method
(DMST), which considers variations in relative wind speed
through the wind turbine. Results from both, CFD simulation
and DMST model, applied to the micro turbine are presented
