The objective of this project is to train and unerstand the behavour of the air around a car, and the drag that it produces. The simulation will be an incompressible fluid that flows around the shape of a car.

The aim of this project is to find the correct coefficient of drag (cD) for a Helium filled party balloon of 0.8m diameter.
The simple sphere and the most common natural shape of balloons are investigated.
Steady state k-omega SST CFD simulation will be used for this purpose since it is the most commonly used type for external CFD simulations.
In order to find a correct value one has to provide a correct mesh for this setup. Later this will be discussed in the comment section below.
