A wind turbine refers to a type of machine that converts kinetic energy into electrical energy. It converts wind energy into electricity by utilizing the aerodynamic forces, which involve lift and drag. These forces are generated by the rotor blades, which function similar to rotor blade of helicopter or wing of an airplane. Wind turbines are a significant source of intermittent renewable energy, which can help in decreasing the reliance on fossil fuels and thereby reducing the energy costs. Smaller wind turbines are employed for tasks such as powering traffic warning signs and battery charging for caravans or boats. Larger turbines can aid household power supply and their extra energy be added back to the electrical grid. This book aims to shed light on some of the unexplored aspects of wind energy aerodynamics and the recent researches on this topic. It contains a detailed explanation of the aerodynamics utilized by wind turbines. The book will help the readers in keeping pace with the rapid changes in this area of renewable energy.

A wind turbine converts wind energy into electricity by utilizing the aerodynamic force of the rotor blades. The blades of the wind turbines are developed by using the aerofoil structure, which is also frequently utilized in the construction of airplane wings. There are many distinct varieties of wind turbines, and each one generates electrical energy using a unique idea. Lift and drag are the two significant aerodynamic forces utilized by wind turbines. The wind turbines which use drag forces contain a vertical rotor and are based on the concept of air resistance. The lift propelled wind turbines contain blades which are positioned perpendicular to the wind direction. The maximum speed of air resistance wind turbines cannot be greater than the speed of wind but lift propelled wind turbines can rotate faster than the speed of the wind. This book elucidates the concepts and innovative models around prospective developments with respect to wind turbines and their aerodynamics. It is a resource guide for experts as well as students.
