Wake reduction in horizontal axis wind turbine: A review of advancements in techniques

What is it about?

Our newest addition to the field of wind turbine engineering. We have changed the perspective of classifying the problems and reduction techniques for wake effects emanating from wind turbine blades. Wind turbine wakes are a major family of problems plaguing wind farms. It has often been viewed from the standpoint of problem categorization but here we have changed the perspective of viewing the problem. We have reviewed the possibility of solving wake-problems from the viewpoint of viability of workable solutions. Thus, effectively providing a solution matrix of active and passive techniques that best handle wake interaction problems on wind farms.

Why is it important?

This paper is expected to be of special interest to energy professionals involved with installation of wind farms, to aerodynamics professionals dealing with wake phenomenon in free vortex flows and experimental/computational fluid dynamists investigating techniques for wake reduction. Moreso the paper will provide a renewed view of the wake-induced problems for post-graduate students investigating blade induced disturbances and their interaction effects.
