In the recently published ‘ Small wind generation using complex airfoil turbine ,’ researchers from Taiwan 3D printed a small wind turbine for small power generation in public utilities like streetlights.
The use of wind turbines continues to increase around the world, and as the researchers remind us—wind is an infinite source of power; however, its supply at a particular place and time is not always guaranteed. Variations in speed are a big reason for erratic power generated by turbines—of which there are two types: horizontal axis wind turbine (HAWT) and vertical axis wind turbine (VAWT).
Historically, many researchers have attempted to refine turbine efficiency, especially those with smaller components. Variable pitch blades may solve torque issues, while the use of different blade angles increases power. Force and velocity vector acting on the cross section of a VAWT blade. Today, an affordable power generating system for cities that have […]
