2. Design and analysis of domestic windmill blades

3. FLOW OF CONTENTS Introduction of windmill Components of windmill
Blade design parameters
Softwares used
Blade models
Result analysis
Future scope of our project
conclusion

4. PROBLEMS
Now a days we meet lot of power demands. In order to fulfill this power requirement go for non renewable such as nuclear, thermal & coal power generation.
These plants are pollute the environment.
Fuel cost is also increased every year. 1

5. OBJECTIVE
To Design and Analyse of domestic wind mill blades for getting the optimum design.
Reduce the pressure effects on the blades.
Increase the life of the blades.

6. INTRODUCTION OF WINDMILL
Windmill is one of the renewable energy resource.
Motion of air is called wind.
In wind energy power generation, USA is first place.
In our world, India is fifth place in wind energy power generation.
In India, Tamilnadu ninth place in wind energy power generation.

9. PRINCIPLE OF WINDMILL Kinetic energy Mechanical energy
Electrical energy

10. BLADE DESIGN PARAMETERS
Wind speed (m/s)
Cut-in speed (m/s)
Cut-out speed (m/s)
Tip speed ratio
Blade chord
Swept area
Rotor diameter

11. METHODOLOGY Solid works – To design the Windmill blade model
Ansys-CFD – To analyze the models

12. DESIGN OF BLADE
We considering the following parameters for design the blade.
Length of blade = 9200 mm
Width of blade = 450 mm
Thickness of blade = 135 mm
Blade material = carbon fiber reinforced composite

14. BLADE DESIGN 2

15. BLADE DESIGN 3

16. ANALYSING PROCEDURE STEP I – IMPORTING GEOMENTRY
STEP II – MESH GENERATION
STEP III – CREATING NEW SIMULATION
STEP IV – IMPORTING THE MESH
STEP V – DEFINING THE SIMULATION IN ANSYS CFX-pre
STEP VI – SOLVE THE PROBLEM
STEP VII – POST PROCESS THE RESULTS

23. CONCLUSION
The project carried out by us will make an impressing mark in the field of renewable energy.
This project we are study about the domestic windmill blade.
Doing this project we are study about the 3Dmodelling software (SOLIDWORKS) and Study about the analyzing software (ansys) to develop our basic knowledge to know about the industrial design.

24. From these three models of blades the power will remain constant
From these three models of blades the power will remain constant. But the pressure on the blades are varied. From that choose the best design.
Frist design optimum blade design.
The life of the blade is increases due to the selection of the best design.

25. FUTURE SCOPE
Wind energy is renewable sources so we have to generate power for long period.
Pollutions are reduced and economical power production.
In other plants the fuel cost will increases so the cost for production is more.
Wind energy independence from the climate condition .so we have to generate the power for any time.
