Experimental Investigation of a Vertical Axis Savonius Wind Turbine

Abstract

Wind turbines are machines that convert wind energy into energy usable by humans. These include wind turbines that produce electricity or those that pump water. There are many models of wind turbines.This report proposes to study an experimental part of a Savonius vertical axis wind turbine. We then define the efficiency of our Savonius wind turbine by its energy (the electrical output power over the kinetic power of the input wind). The parameters studied are varied: geometric configuration of the rotor, influence of the speed of the wind, influence of the generator, The study was carried out using a blower (reverse mode of a vacuum cleaner), The one of the shortcomings of the Savonius model is its relatively low efficiency, it is interesting to know which energy transformations (transformation of wind energy into mechanical energy of rotation, and transformation of mechanical energy of rotation into electrical energy) lead to yields so weak.
