The book presents the basics ideas about wind energy and the continuous development in the field. It reviews about the available VAWT/HAWT, airfoil theory, and Betz Law. Further, it explains about the determination of various parameters associated with wind energy like: pressure distribution, co-efficient of pressure, wind power, lift, drag etc. for a symmetrical as well as for non-symmetrical airfoil cross-section. The analysis of pressure distribution and pressure coefficients distribution has also been presented for various airfoils to select one for VAWT and the velocity profile of wind...
