“…We will assume a 3 parameter profile. It has been observed that a turbine wake can be divided into multiple regions 1,2,6,7,13,14 , each with their own energy diffusion processes. For convenience we will consider two distinct regions; A core flow where the velocity deficit is constant, and a shear disk where velocity recovers to the free stream value at the wake edge as in figure- Figure (xx7?).…”

“…This method of control has been shown to be more effective than TSR control at increasing cluster efficiency and reducing unsteady loads [XX]. 13 An analytical model of yaw deflection has been derived by Jimenez 15 based on high fidelity CFD solutions. The model inputs are the non-yawed axial induction factor aj and the turbine yaw angle γj.…”

“…In the above power expression, we have the factor cos(γ n ) 3 with exponent 3. In literature such as, e.g., (Gebraad et al, 2014a) and (Medici, 2005) (page 37), numerical values for the exponent were given according to LES and wind tunnel data, respectively. However, to date, the exact value for it is still under research and since this is outside the scope of this study, the value of the exponent will be three.…”

“…In [4] a simple yet widely used wake model is employed to model the wake effect, while [3] uses a finite volume discretization of the Navier-Stokes equation for the wind flow model. In another method which is presented in [7], the authors suggest deflecting wakes by yaw-misalignment in order to reduce their effect on the downstream wind turbines.…”
