Abstract
The utilization of wind power has been a sustainable way for renewable energy utiliza-
tion in developing countries. The operation of water pump by wind energy has been used
for many years. The project is about designing and fabricating a Helical Savonius wind
turbine for water pumping application. The Helical Bach design was selected because of
simplicity in design, producibility, efficient and able to operate at very low-wind condi-
tions. The blade modeling was done in SolidWorks and analysis was done in ANSYS
2021. The fabrication process involves the selection of appropriate materials, design of
rotor and shafts, followed by manufacturing and assembly of the components. The ex-
perimental study was done at the average wind speed ranging from 1.1 m/s to 4 m/s. The
torque was measured using rope brake dynamometer setup. The CFD approach used for
study at the wind speed of 4m/s and Tip speed ratio(TSR) of 0.32 calculates the coefficient
of performance (Cp) to be 0.107 and in experimental found to be 0.025. The maximum
average wind speed that the turbine was tested was 4 m/s with a rotational speed of 48.18
rpm. The cut-on speed was found to be 1 m/s. Overall, this project demonstrates the
potential of Helical Savonius wind turbine for water pumping applications in low wind
speed conditions thus facilitating the country for promoting indigenous and sustainable
energy resources for low carbon development path.
Description
Today, wind turbines can generate even more energy to power water pumps than tradi-
tional windmills, which have been used to pump water for centuries.As a general rule,
wind energy is used to pump water through a pump driven by a wind turbine. A wind
turbine generates electricity, which is then used to power an electric motor to drive a wa-
ter pump.
