4. Abstract
 Wind is a renewable source of energy which can be converted to other useful forms of
energy, turbine is a device which converts this wind energy into power output with the
help of generator.
 In this study, modification on hybrid design of vertical axis wind turbine by combining
savonius and darrieus blades has been demonstrated in order to increase the energy
yield obtained from wind energy.
 In near future the world will shift towards renewable energy source for global warming
and energy needs.

5. Introduction
 Wind turbines are divided into two groups ,namely horizontal and vertical
 VAWT can capture wind from any direction, while in HAWT have a mechanism in
which they face towards wind direction
 HAWT are usually more efficient than VAWT

6. Introduction
 Savonius rotor is self starting turbine.
 Darrieus rotor is not self starting, lift based and is very efficient
 The hybrid design is a combination of two rotors namely, Savonius and Darrieus
mounted on same shaft
 The curved shape of savonius blades allowed them to capture wind energy from
any direction, which is especially use in low wind condition
 Darrieus blades vertically and evenly spaced around the central axis to ensure
balance and stability. The design is more efficient at higher wind speed and
generate consistent power.
 Savonius blades are omnidirectional and can capture wind from any direction,
while Darrieus blades are typically more efficient in their orientation.
 By combining both blade types, the VAWT can harness wind energy effectively
across a wider range of wind speeds, which improves overall efficiency.
 This combination of blade types allows for a more consistent and higher overall
power output compared to using either blade type alone.
 The yield output depends on the location of installation and the nature of wind
flow
 The Savonius and Darrieus VAWT are mostly installed in urban environment

7. Objective
 The objective is to design and build a vertical-axis wind turbine that merges Savonius
and Darrieus blade designs, aiming to maximize energy output, enhance efficiency,
ensure versatility, and maintain cost-effectiveness.
 This innovative turbine should contribute to sustainable energy generation, reduce
greenhouse gas emissions, and advance wind energy technology while providing a
practical solution for a cleaner and more reliable electricity source.

8. Renewable Energy
 It is derived from natural processes that are replenished constantly
 Reused
 Available in wide spread
 Free from pollution
 Clean and pure energy
 Can be used to tackle global warming, increasing population density and other energy
crisis problems
 e.g solar, wind, ocean, hydropower, biomass, geothermal resources.

 Cheaper to produce
 Easily installed
 Functions in variable wind conditions
 Transportable
 They can capture wind from any direction ,they don’t need to face towards the wind
like in HAWT

 In, conclusion our journey through the world of wind energy and the fusion of Savonius and Darrieus
blades in a vertical-axis wind turbine has been a thrilling one. We've harnessed the power of innovation
and combined the strengths of two blade designs to create a truly remarkable turbine.
 As we stand at the crossroads of sustainable energy and environmental responsibility, remember that the
future is in our hands. By pushing the boundaries of design and technology, we have the potential to
shape a cleaner, greener, and more sustainable world.
 The winds of change are blowing, and they carry with them the promise of a brighter, more eco-friendly
future. Let's harness that potential, continue to innovate, and work together to build a world where
renewable energy reigns supreme.
