Small Wind Turbines: Analysis, Design, and Application

摘要

The book aims, according to comments in the Preface, "to provide basic analysis and design guidelines to allow... engineering undergraduates or junior engineers to design and build a small wind turbine." Small turbines are defined to have less than 50 kW of rated power and 200 square meters of area swept by rotating blades. The lower Reynolds number and higher rotational speeds of small wind turbines cause particular differences in aerodynamics and stress analysis. Only horizontal-axis turbines are addressed. The book provides the reader with useful formulas and some explanation of their foundation and purpose. However, in areas of foundational science, such as fluid dynamics and structural mechanics, it is much more of a handbook than a treatise on engineering science. For example, the Navier-Stokes or Euler equations are not discussed. Rather, the conservation equations for fluid motion are presented in integrated or partially integrated forms; for example, balances are made on thin annular streamtubes.
