Abstract
The efficiency of cooling system is critical for wind turbines, particularly
during the hot season, when high temperatures could damage the electric
generator and mechanical parts of the turbine. The cooling system proposed in
this paper is able to increase the efficiency of heat transfer with the use
of nanofluids and the wind turbine tower as a heat exchanger to dissipate
waste heat in the environment. In this study the use of Al2O3-water
nanofluids has been considered. The results of this investigation appear
encouraging because they have shown that the proposed new solution is able to
assure highly efficient heat transfer and to limit thermal stresses on the
electrical and mechanical components of wind turbines.
