Muhamad Fadhil Maulana Savonius Wind Turbine Power Calculator

Estimate design is made according to the calculation above and from reference from a reference journals linked below. I estimate the gaps between tollways to be 1 meter but it can be changed according to the specific tollways the savonius wind turbine is going to be used.

The diameter for the wind turbine is 900mm wide, 2 blades, overlap ratio of 0, and turbine height 1 meter. According to the calculation it can produce Theoretical Power of 551.25 W and hourly Energy Output of 99.22 Wh.

Inital design and measurement of the wind turbine. CFD analysis haven't been conducted yet.

For the shaft of the turbine, the possible design and mechanism is the following :
