Extract of sample "Wind turbines"

Download file to see previous pages According to studies, wind contributes only less than 1% of the world's energy needs (Grose 1). Even if the percentage of contribution is very low, the use of wind turbines as means to generate electricity grow continuously. This is because people nowadays discover the good benefits of using wind turbines in terms of environmental factors.
However, some disadvantages still prevent other people from using wind turbines and few of these reasons are related to high cost of manufacture and noise created by these machines (Mahoney 2). Ongoing improvements on the blade's design and material are continuously done to further develop the machine in terms of its aerodynamic properties and performance.
A wind turbine is a machine that can generate electricity through the use of wind power. A wind turbine has large rotating blades that are capable of capturing wind and creating kinetic energy. This energy is converted to mechanical energy which is used to generate electricity for various purposes (Mahoney 1). Shown below are the parts of a typical wind turbine:
The horizontal axis wind turbine (HAWT) is also known as the classical or most commonly used wind turbine in the world. The axis of rotation of these turbines is horizontal to the ground and parallel to the wind stream (Mathew 16). Shown is a diagram showing a sample of a horizontal axis wind turbine.
Shown is a diagram showing a sample of a horizontal axis wind turbine.
The advantages of using HAWT are its structural stability and changeable blade pitch that allows greater control of the turbine and aids the blades in catching the maximum amount of wind. Versatility is also seen as one of its advantage in terms of its ability to be feathered in case of storms (Mahoney 1).
2.2.2. Vertical Axis Wind Turbine
Vertical axis wind turbine (VAWT) is different from HAWT because it is vertical to the ground and almost perpendicular to the wind direction. The VAWT can receive wind from any direction and so, complicated devices are avoided. The advantage of using VAWT is that they are not needed to be built very high. Maintenance is also easier since the VAWT is located nearer to the ground. The design is also not complicated and blades can easily be seen by birds (Mathew 19).
On the other hand, VAWTs are less efficient than HAWTs since they can only produce energy that is 50% of what HAWTs can produce. Another downfall of VAWTs is that it can only rotate faster in higher elevations and with high wind velocity. Lastly, the turbine must be dismantled first in order to change or repair some parts when necessary (Mathew 19).
Shown in diagram 2 is a sample of a vertical axis wind turbine.
2.3. Types of Horizontal Axis Wind Turbine Blades
Wind turbine can be classified as single bladed, double bladed, and three bladed. The cheapest among the four classifications is the single bladed wind turbine since it only consumes small amount of material and labor. On the other hand this design is not ideal since balance is also an important factor in wind turbine construction and single bladed wind ...Download file to see next pagesRead More

Wind Tunnel Use

...Wind tunnel use Fundamentals a) Explain how lift force is generated ( include a sketch of a typical cambered aerofoil).? An aerodynamic force is produced by any body which moves inside a fluid. The component of this force which is perpendicular to the direction of motion is called Lift. On the contrary, the force in the direction of motion is called the drag. The Lift force is created according to the hydrostatical theorem of the Archimedes principle. According to this principle, the aircraft will be buoyed up by a force equal to the weight of the air displaced by the aircraft. (Milne-Thomson, 1966) An aerofoil is a perfect example to discuss the creation of the lift and the reasons associated with it. An aerofoil is a non-symmetric...
