TITLE: DESIGN AND FABRICATION OF VERTICAL AXIS WIND

"A Savonius is a type of vertical axis wind turbine (VAWT) generator invented in 1922 by Sigurd Johannes Savonius from Finland though similar wind turbine designs had been attempted in previous centuries."

The Role of an Inverter in Off-Grid Wind Power Systems

An essential component in off-grid wind power systems is the inverter. The primary function of the inverter is to convert the DC (direct current) electricity produced by the turbine into AC (alternating current) electricity that can be utilized and distributed within the grid. By optimizing the performance of an inverter, energy yield from the wind []

Computational Study of Submerged Air Inlet Performance

Mossman9 tested two submerged inlets in a wind tunnel with parallel and divergent ramp walls.

Then, how much power can be captured from the wind? This question has been answered in a paper published in 1919 by a German physicist Albert Betz who proved that the maximum fraction of the upstream kinetic energy K that can be "absorbed" by an ideal "actuator" – not necessarily a turbine, but any device capable of converting wind energy to another energy form– is (
