Mathematical Toolbox and its application in the Development of Laboratory Scale Vertical Axis Wind Turbine [PDF]

open access: yes, 2018
A wind turbine works with the principle of extracting energy from the wind to generate electricity. The power generated is directly proportional to the wind speed available. There are two major types of wind turbine design namely the horizontal and vertical axis wind turbine depending on the orientation of the turbine rotor and its generator.
