The recently developed k-ε-fP eddy-viscosity model is applied to one on-shore and two off-shore wind farms.The results are compared with power measurements of the standard k-ε model.In addition, direction uncertainty used correct a Gaussian filter.The underpredicts deficit first downstream turbines, whereas eddyviscosity shows good agreement measurements.However, difference in predicted by turbulence models becomes smaller for turbines that located further downstream.Moreover, between capability estimate farm efficiency, reduces increasing size turbine spacing.
