The purpose of this paper is to explore and define an adequate numerical
setting for the computation of aerodynamic performances of wind turbines of
various shapes and sizes, which offers the possibility of choosing a suitable
approach of minimal complexity for the future research. Here, mechanical
power, thrust, power coefficient, thrust coefficient, pressure coefficient,
pressure distribution along the blade, relative velocity contoure at different
wind speeds and streamlines were considered by two different methods: the
blade element momentum (BEM) and computational fluid dynamics (CFD),
within which three different turbulence models were analyzed. The
estimation of the mentioned aerodynamic performances was carried out on
two different wind turbine blades. The obtained solutions were compared
with the experimental and nominal (up-scaled) values, available in the
literature. Although the flow was considered as steady, a satisfactory
correlation between numerical and exp...erimental results was achieved. The
comparison between results also showed, the significance of selection,
regarding the complexity and geometry of the analyzed wind turbine blade,
the most appropriate numerical approach for computation of aerodynamic
performances.
