Tidal turbine performance enhancement through winglets

Tidal turbine performance enhancement through winglets

This project looks at whether winglets could provide enhanced performance for tidal turbines. They have been successfully used in non-rotating applications such as passenger aircraft but only limited use in rotating applications, most notably on Enercon wind turbines.

Experimental study of the effect of fitting winglets to a tidal turbine

The projects aim is to study the effect of adding winglets to a 1/20th scaled tidal turbine, and measure their impact on the Power and Thrust coefficients (CP and CT). In theory, an increase in the CP would be a result of the reduction of any tip losses. Previous CFD simulations and experiments carried out on wind turbines suggest that a winglet facing the suction side with a height of around 4% and a 25% radius would be optimal for this purpose.
