WIND TURBINE

-



Wind turbine is a mechanical device which converts the kinetic energy of the moving wind to the electricity energy. People are using mechanical devices to convert wind energy in mechanical energy from pre historic times. Wind turbines are great source of getting green and renewable energy. They can be installed at any place fulfilling two qualities huge free space and moving wind

Types of wind turbine

There are many ways in which you an classify wind turbine but following are the two most widely used and known types of wind turbine 
1. Vertical axis wind turbine
2. Horizontal axis wind turbine
Vertical axis wind turbine have axis of rotation of their blades vertical to ground on which they are installed and horizontal axis wind turbine have axis of rotation parallel to ground.

Parts of wind turbine

Each wind turbine needed different parts on the basis of its type and working condition but following is the list of parts that are present in most of the common turbine

 1. Hub
2. Rotors blades
3. Shaft (low speed)
4. Shaft (high speed)
5. Pitch mechanism
6. Electrical Brake
7. Mechanical Brakes
8. Gear box
9. Generator
10. Converter
11. Wind sensor
12. Yaw drive
13. Yaw motor
14. Tower
15. Nacelle
16. Guide wire ( only in vertical axis wind turbine)

Working of wind turbine

Working of wind turbine is quite simple, everyone know that moving wind have kinetic energy and this energy is converted into the rotation motion of blades of a wind turbine when wind strike on the turbine blade. Blades are attached to shaft so as the blades move shaft also start to move. This shaft is attached to a gear box which increase or decrease its speed according to the turbine design. After the gear box shaft is attached to a generator whose rotation causes the production of electricity.

Advantages of wind turbine

1. Produce the electricity in clean and natural friendly manner
2. Wind energy is available almost every where
3. It is renewable source of energy
4. Produce electricity at low prices
5. Remote areas that are not connected to the electricity power grid can use wind turbines to         produce their own supply.
6. Reduce the dependence on fossil fuel

Disadvantages of wind turbine

1. Created noise pollution
2. Bad visual impact
3. Cover huge area
4. High initial cost 
5. High maintenance cost
6. Not a constant source of energy

To understand the deflection of beam Objective of  deflection of beam lab report 1. Learn basic working of beam 2. Perform theoretical calculation for deflection of beam 3. Perform series of experiment with different material, shapes and load  for beam 4. Compare the result and Discuss the finding Introduction to  deflection of beam Load supporting element in any structure that is installed in horizontal direction and take load perpendicular to its length is called a beam.   Based on the way it is installed in structure, beam can be classified in to four main types.  First simply supported beam which have supports at its both ends, second is overhanging beam which have length extended over its supports, third is overhanging beam which have more than two supports and fourth is cantilever beam which fixed only at one end and other end is free.  There are three basic types of supports available for beams which includes fixed ends support, pined connection support and roller end support.

Aim of Bending Moment in a Beam Aim of this experiment is to study effect of force magnitude on bending moment of beam Recommended:   Deflection of Beam Lab Report Theory Bending Moment in a Beam Beams A structural element which is designed and used to bear high load of structure and other external load is called beam. There are many different types of beam like cantilever beam, simple supported beam and overhanging beam.  Bending of Beam When an external load or the structural load applied in beam is large enough to displace the beam from its present place, then that deflection of beam from its resent axis is called bending of beam.  Bending Moment In simple words bending moment is the product of force applied on beam with the distance between the point of application of force and fixed end of the beam Introduction to Experiment of Bending Moment in a Beam This experiment is about studying the effect of force magnitude on bending of beam and for that structure hardwar

Aim of Bernoulli experiment Aim of this experiment is to compare the behaviour of ideal fluid and real fluid using Bernoulli experiment. Objective of Bernoulli Theorem 1. Use the venture meter apparatus to perform Bernoulli experiment and the effect of area of the flow velocity and fluid pressure 2. Use the Bernoulli’s equation /  Bernoulli theorem  to compare the behaviour of ideal and real fluid Introduction  Bernoulli Experiment According to the Bernoulli’s experiment when area available for the fluid to flow decrease then flow of fluid increase and at the mean while time the fluid pressure or the fluid potential energy decreases. Read about the Effect of Sluice Gate on the Flow of Fluid .  This principle was name after the Daniel Bernoulli who first writes this principle in book named Hydrodynamic.  Following are some of the application of the Bernoulli experiment Find the Air-flight Lift Baseball Draft Sailing Theory of Bernoulli's Theorem Experiment According to Mil
