Performance Improvement of Turbine Blade Using Flow Control Techniques: A Review

Utilization of wind energy has become an emerging concept for clean energy generation due to its vast availability, low cost and its contribution to carbon dioxide reduction. Wind turbines are the prominent converter which are used in both onshore and offshore wind energy generation projects. The performance of the wind turbines manly depends on blade aerodynamic performance. The aerodynamic performance of blade can be enhanced by using flaps, vortex generator, airfoil modification on leading or trailing edge, slots in airfoils, etc. The present paper mainly focuses on different passive flow control techniques, especially Gurney flap and vortex generator are used for enhancing blade aerodynamic performance.
