Wake measurements were performed using kite anemometers at the Goodnoe Hills MOD-2 site. The objectives of the work were to take measurements to define the wake and to verify the numerical wake model that treats wake similarly to jet-like flow. It is found that essentially two principal parameters govern wind turbine wakes - the thrust force that the turbine exerts on the flow, which determines the initial velocity or momentum deficit, and the ambient (free stream) and mechanical (wake) turbulence which control wake expansion and therefore wake velocity deficit decay. The basic wake theory equations for application to a wind turbine are developed and discussed, and measurement data and associated error are calculated and compared to the model. (LEW)
