This module introduces the principles of wind energy and the fundamental difference between wind shear and wind gradient. The various categories of the Beaufort scale are discussed as well as the primary forces that affect wind speed and direction. The purpose of a geographic coordinate system is described, and a comparison of angle of attack and lift to drag ratio is presented. The impact of the Betz limit on wind efficiency is covered, along with the fundamentals of Blade element momentum (BEM) theory. In addition, the student will learn how to calculate the tip speed ratio of a wind turbine and how to determine the power coefficient.
