|Abstract:||Wind turbine aerodynamics remains a crucial area of research in the field of sustainable energy. Major challenges faced are problems associated with adverse aerodynamic loads encountered by wind turbines during operation. These problems, found to have a significant impact on the efficiency and life span of the wind turbines, advanced the studies and works for aerodynamic control methods for mitigating adverse aerodynamic loading on wind turbines. This work explores the feasibility of an innovative method of active airflow control to improve the performance of wind turbines using Dielectric Barrier Discharge (DBD) plasma actuators. These devices are capable of manipulating and modifying the flow field around a profile wall resulting to flow changes similar to those observed when the geometry of the profile itself is altered. The advantages of these devices being fully electronic without heavy and complex moving parts presents a great potential as being a viable active airflow control alternative to the wind industry. Discussions presented in this work have concurrently demonstrated that flow separation is delayed through the use of DBD actuators on the profile walls and may be practically applied to wind turbines. This indicated that with the use of DBD actuators, wind turbines may be capable of operating at higher angles of attack, with better operating efficiency and a longer lifespan.|
