N2 - Standard blade element momentum(BEM) codes <br/>use Prandtl’s tip-loss correction which relies on simplified <br/>vortex theory under the assumption of optimal <br/>operating condition and no wake expansion. A <br/>new tip-loss correction for implementation in BEM <br/>codes has been developed using a lifting-line code <br/>to account for the effect of wake expansion, roll-up <br/>and distortion under any operating conditions. A <br/>database of tip-loss corrections is established for further <br/>use in BEM codes. Using this model a more <br/>physical representation of the flow and hence a better <br/>assessment of the performance of the turbine by <br/>BEM codes is expected.
