About the Book
Focusing on aerodynamics of wind turbines, this book presents advanced topics including: Basic Theory for Wind turbine Blade Aerodynamics; Dynamics-Based Health Monitoring and Control of Wind Turbine Rotors; Experimental Testing of Wind Turbines using Wind Tunnels with an Emphasis on Small-Scale Wind Turbines under Low-Reynolds Numbers; Computational Methods; Ice Accretion for Wind Turbines and Influence of some Parameters, and; Special Structural Reinforcement Techniques for Wind Turbine Blades. Consequently, for these reasons, Aerodynamics of Wind Turbines will attract readers not only from the wind energy community but also from the gas turbines heat transfer and fluid mechanics community.
