AERODYNAMIC WHAT IS IT????
Have you ever wondered why cars
have spoilers or why your hand ‘floats’ when you hang it out the window of a
moving car? These mysterious interactions between objects and air have long
been studied and are known collectively as aerodynamics.
Aerodynamics basics -what are they?
Using the principles of
aerodynamics, you can systematically understand the forces that are
acting on an object due to the movement of air around it. Drag and
lift are the two principle forces. On a macroscopic level, by looking
at the momentum of each air particle, it is possible to also predict the
movement of air around objects.
DRAG?
Drag is essentially air
resistance. Drag is the force that a moving object feels when the flow
of air around it becomes turbulent.
Here is a simple example: Imagine
riding a bike with a parachute attached. You will have to do a lot more work
because the parachute adds drag.
What about Lift?
By slowing or increasing the air
velocity around an object, it is possible to change the pressure on the object. If there is more pressure on one side of an object, it will
result in a force, which can propel the object. This principle is used on
airfoils to generate lift
Is that it??
That’s the basics of aerodynamics,
but there is a lot more to learn! The principles of aerodynamics are widely used in
the automotive, aerospace and civil industries. Aerodynamicists try to
optimise the the geometry of objects to make them more efficient. In civil
applications, these principles are used to predict the flow of air within and
around buildings. Once you understand the basics of aerodynamics, you will see
their applications all around you, from aircraft wings to boats to turbine
engines.
