A partially static turbine—first experimental results
Grassmann, H.; Bet, F.; Cabras, G.; Ceschia, M.; Cobai, D. - In: Renewable Energy 28 (2003) 11, pp. 1779-1785
Recently it has been shown in a fluidodynamic simulation, that a wing-profiled structure of rather small size placed in the vicinity of a wind turbine augments the power of the wind turbine. In this paper we present the first experimental results from a prototype.
