There is huge potential for smaller wind turbines to provide clean energy around the world. Small wind turbines come in a variety of designs, and have similarities in principles and technology to small hydrokinetic turbines (SHKTs). SHKTs, in turn, can play an important role in hydropower. Small wind and hydrokinetic systems can even work together, for example, to power farms, communities, campuses, rural as well as remote rural areas, and island regions. This concise book, written by experts in the field, provides an in-depth overview of small turbines for wind and hydropower. Chapters cover resource assessment for wind and water, turbine technology, design of vertical and horizontal axis turbines, blade element analysis, vibration-based energy harvesting, very low head turbines, diffuser augmented wind turbines, and numerous case studies.
Wind turbines extract kinetic energy from the wind. Hydroturbines can either extract energy from water flow or use the potential energy due to a difference in elevation or “head”. This book considers kinetic-energy-extracting wind and hydro turbines although two later chapters will show that the boundary with head-driven hydroturbines is somewhat artificial. One of the major differences between large and small turbines is that the basic technology of the former – three upwind blades rotating on a horizontal axis – is fixed whereas there is a rich diversity of small turbine designs. This book provides examples of energy-harvesting devices, vertical-axis and diffuser-augmented turbines to display that diversity and to give the reader an appreciation of the challenges of moving from theory to practice. One particularly important challenge for turbines of all sizes is the need to move away from unsustainable materials for turbine blades, primarily petroleum resin and fibreglass.
Small Wind and Hydrokinetic Turbines is a valuable summary for researchers involved with small wind turbines and SHKT development and deployment, both in academia and industry, for research on powering remote areas, as well as for advanced students and manufacturers of turbines.
