Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
Currently, there’s enough wind power capacity in the U.S. to generate enough electricity to power more than 15 million homes, helping pave the way to a clean energy future. What is a Wind Turbine? The concept of harnessing wind energy to generate mechanical power goes back for millennia .
Determine basic configuration: orientation and blade number. take site wind speed and desired power output. Calculate rotor diameter (accounting for efficiency losses) Select tip -speed ratio (higher Æ more complex airfoils, noise) and blade number (higher efficiency with more blades).
Wind power quantifies the amount of wind energy flowing through an area of interest per unit time. In other words, wind power is the flux of wind energy through an area of interest. Flux is a fundamental concept in fluid mechanics, measuring the rate of flow of any quantity carried with the moving fluid, by definition normalized per unit area. For
