This book deals with horizontal-axis wind turbine aerodynamic performance prediction methods. It focuses on the traditional and newly-developed methods for the wind turbine aerodynamic performance calculation. The fundamental theories of fluid mechanics essential for understanding the other parts of this book are firstly introduced in Part I, followed by the blade element momentum theory in Part II, with special attentions to a systematic review of various correction models. Part III is mainly about the prescribed and free vortex wake methods, while the state-of-art computational fluid dynamics (CFD) methods are detailed in Part IV. Part III thoroughly describes the prescribed and free vortex wake methods which are still of great importance towards realistic investigation of wind turbine performance. Despite the highly computational cost, the CFD methods in Part IV have received increasing interest from the academic community since they provide more detailed information about the flow field around the wind turbine. This has shed a light in combination with the correction models introduced in Part II on more advanced research for wind turbine. This book is intended for researchers and students interested in aerodynamics of wind turbine and is particularly suitable for practicing engineers in wind energy. Readers can gain a comprehensive understanding in both classical and up-to-date methods for the study of wind turbine aerodynamics. The authors hope that this book can promote the research and development of wind turbines.

Tongguang Wang, Professor of Aerodynamics at Nanjing University of Aeronautics and Astronautics (NUAA), is the Chair-Direct of the Chinese Wind Energy Association. He received his Bachelor's degree and Master's degree in engineering from NUAA in 1983 and 1988, respectively, with his master's dissertation "Calculation of the Horizontal Axis Wind Turbine Aerodynamic Performance in Different Wind Conditions". He joined the University of Glasgow as a visiting scholar in 1995 and then did his PhD there from 1996 to 1999 and obtained his Degree of Doctor of Philosophy with the dissertation "Unsteady Aerodynamic Modelling of Horizontal Axis Wind Turbine Performance". He did postdoctoral research at the University of Glasgow from October 1999 to August 2001 on orthogonal blade/vortex interaction. During this period, he was invited to join in the Wind Turbine Unsteady Aerodynamics Experiment - Blind Comparison.
