How to learn aerodynamics ?
Aerodynamics is the study of flow of air over any object. When an air flows over any object there is creation of forces over it such as lift and drag. These forces are created due to pressure differences over the top and bottom surfaces.
One of the methods to learn aerodynamics is by simply visualizing. Aerodynamics can be learnt by seeing the flow of air over our car, or any other vehicles, while riding a bike, or by driving and just sitting in our cars.
When we ride any bike we have flow of air over our body, which in general gives some resistance to the flow of air. This is also aerodynamics. We can reduce the air resistance by tilting our body forward. When we are in a car and put our hand outside we also see the flow of air and feel resistance to it. These are the cases of aerodynamics. If we slightly bend our palm to the direction of flow of air then there is less drag. However, these methods should not be done at a high speed of the car, otherwise it can cause injury.
Use of aerodynamics is also in aircraft. We see aircrafts and helicopters. Aircrafts are the perfect example for the use of aerodynamics. Wings of the aircraft generate lift, which is the main source of force for uplifting the aircraft from the ground and flying in the sky. Similarly, helicopters use aerodynamics through the use of its rotor and blades in order to lift up and fly forward into the sky. Rockets and spacecraft also use aerodynamics.
Racing formula cars use streamlined bodies in order to move faster and reduce drag to a significant amount. Cricket balls are a fine example of aerodynamics. We can swing any ball by the use of seam.
In our home we can make a small wind tunnel in order to study the flow behavior over any object. Similarly, wool tufts and fan can be used to visualize the flow of air. In the present day, we can use modern technologies like computers in order to study aerodynamics with the use of computational fluid dynamics or (CFD). These are very cost efficient and are also used by many industries.
