Construction of a helical vertical axis wind turbine for electricity supply

Abstract

In an effort to find solutions for global energy crisis, an analysis on a helical vertical axis wind turbine was conducted with the consideration of renewables and energy efficiency. This study was carried out in two steps: the realization of the analytical calculation of a helical wind turbine power output which then informed the design and construction of the rotor blades. The project particularly aimed to address its use as the electricity supply for residential properties or any other places with less ideal economy conditions. The uncomplicated and highly accessible mechanism using basic materials is to give people to have a viable option on their own electricity production.

A comprehensive review on design and development analysis and blade material selection of helical Savonius rotor

“…They found that two stages two bladed twisted Savonius rotors generates maximum power coefficient of 0.31, whereas for the same design configuration C p , max = 0.29 are found from semicircular rotor. Reza et al (2015) studied on power output from helical Savonius rotor, which is depends on design and construction of the rotor blades. The turbine size and operation requirements could be a scalable solution and significant expansion potential to address the current renewable energy demand.…”
