ABSTRACT: In this work
was carried out the aerodynamics design of a 1 MW horizontal axis wind turbine by using blade element momentum theory (BEM). The generated design was scaled and built for testing purposes in the discharge of an axial flow
fan of 80 cm in diameter. Strip theory was used for the aerodynamic performance
evaluation. In the numerical calculations was conducted a comparative analysis
of the performance curves adding increasingly correction factors to the
original equation of ideal flow to reduce the error regarding real operating
values got by the experimental tests. Correction factors introduced in the
ideal flow equation were the tip loss factor and drag coefficient. BEM results
showed good approximation using experimental data for the tip speed ratio less
than design. The best approximation of the power coefficient calculation was
for tip
speed ratio less than 6. BEM method is a tool for practical
calculation and can be used for the design and evaluation of wind turbines when
the flow rate is not too turbulent and radial velocity components are
negligible.
