The simple principle of a wind turbine is known to humankind. Using wind to rotate the turbines to produce electricity. As a result, the propellers tend to turn, and we are exposed to the flow of electricity. But apart from these obvious facts, how does the process take shape? How does it manage to carry on the flow to another source? Well, all these questions are targeted towards the basis of functionality, and yes, we are here to provide all the answers. Hence, go ahead and read all about the functionality of a wind turbine.
The force of aerodynamics plays a crucial role as rotor blades tend to work like an aeroplane wing or a helicopter’s rotor blade. As a result, when wind flows and moves across these blades, air pressure on one side of the blade decreases. Due to that, there will be a difference in air pressure across two sides of the blade and thus creates lift and drag. As the force of the pull is stronger than the force of drag, this causes the rotor to spin.
Since rotors are in turn connected to generators, the speed of the rotation manages to allow these generators to function. At times, these generators are also connected through a series of gears and might not be in direct contact with the turbine. But towards the end, the force of aerodynamics enables generators to function and thus, creates electricity. Due to this process, wind turbines are considered to be a viable source of energy production that relies on renewable energy.
Modern wind turbines tend to fall under two main groups, and their functionality is in sync with the right aspects. As a result, you will come across (a)vertical-axis turbines and (b)horizontal-axis turbines.
a. Vertical-Axis Turbines
Vertical-axis turbines differ from each other through variations in size. Although the basis of functionality for both the types share similar aspects, vertical-axis turbines had two main problems, i.e., lower power generation and frequent braking. But thanks to the latest VAWT technologies, most of these problems have been cleared. Small vertical wind-turbines have been critical in shaping the solution.
b. Horizontal-Axis Turbines
Horizontal-Axis Wind Turbines are more widely used when compared to vertical-axis wind turbines. With a higher yield of aerodynamics, things tend to get a lot more comfortable with these turbines. The many blades that are part of the turbine manage to produce the required amount. Standard horizontal-axis wind turbines have between one to three blades, and it varies based on the aspects of cost, power coefficient and the speed of rotation of the wind sensor. When you consider the extent of outcome and other such factors, you will realise that horizontal-axis turbines have the upper hand over vertical-axis turbines.
