N2 - It is a known fact that the power produced by <br/>wind turbines operating inside an array decreases <br/>due to the wake effects of the upstream turbines. <br/>It has been proposed previously to use the yaw <br/>mechanism as a potential means to steer the upstream <br/>wake away from downstream turbines, however <br/>such a mechanism introduces control complications <br/>due to changing wind directions. Deflecting <br/>the wake in the vertical direction using tilt, on the <br/>other hand, overcomes this challenge. In this paper, <br/>the feasibility of steering wake is explored in <br/>a simple uniform inflow case. This is done by trying <br/>to model the wake deflection as a function of <br/>the yaw/tilt angle and the rotor thrust, initially using <br/>the momentum and vortex theories. Thereafter, <br/>a relatively more promising empirical model based <br/>on a set of actuator disc CFD computations is proposed. <br/>Finally, comments are made on the feasibility <br/>of wake control using yaw/tilt.
