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.

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.

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

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.

• 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.
