Transcript of Development of a Small-scale Vertical Axis Wind Turbine


Development of a Small-scale Wind Turbine as an Alternative Energy Source for Residential Applications


Developing a small-scale Vertical Axis wind turbine with
readily available and cheaper materials may improve
the living conditions of those in isolated rural areas.
Related Studies
Statement of the Problem
Studies on VAWTs on its operation in high wind speed are disregarded. VAWTs designs are often in low wind speed where it cannot maximize its power. Therefore a VAWT that can be operated at higher wind speed should be developed.
Since Philippines is an archipelago,
there are still many places where
energy grid is unavailable,
therefore, no electricity access.
A master's thesis on 2010 by Ambrosio and Medaglia, reviewed different type of vertical axis wind turbines .
A study of Javier Castillo on March 2011 focused on the design of a three bladed small vertical axis wind turbine with wood as a construction material operating in low wind speed
Background of the Study
-The future is in renewable energy- not in outdated and environmentally destructive fossil fuels (Abad, Greenpeace Southeast Asia 2013)
Wind energy in the Philippines

Philippines is abundant in wind
Bangui Bay is the only commercial wind farm in the Philippines
Wind Turbine
- Horizontal Axis Wind Turbine
- Vertical Axis Wind Turbine
Another study on the same year
by Jason Gregg, showed the effects of the number of blades varying wind speed in power generation.
Objectives of the Study
To provide a cheap alternative energy source for residential applications in remote areas using readily available materials
To develop a small scale vertical axis wind turbine that could generate maximum power output in higher wind speed using wood for the airfoils
Significance of the Study
Providing an alternative energy source would improve the living conditions of the residents in the isolated rural areas
Small wind turbine production facility will cost less than a photovoltaic factory of the same capacity
Scope and Delimitation
A straight-bladed Vertical axis wind turbine
Type of wood will be used are Lauan and Apitong
The parameters to be considered will only be the type of wood, size and weight of the blades,power and power coefficient, tip speed ratio and wind speed
Brgy. Pananag-an Borongan City Eastern Samar
Methodology
-Data Gathering
- Determine the parameters for maximum output
-Design of Wind Turbine
-Final Output
Pw = ½ ρS Vo^3
Where:
Vo = velocity of the wind in m/s
ρ = air density in kg/m^3

Power
Tip Speed Ratio
TSR = Tangential speed at the blade tip = Rw/Vo
Actual wind speed
Where:
R = rotor radius in m
W = angular speed in rad/s
Vo = wind speed in m/s

Power Coefficient
Cp = Captured mechanical power by blades/
Available power in wind
