Simulation of lateral stability of a Thrush S-2R crop duster at high yaw and angle of attack. This airframe was originally designed for radial engines, so the addition of an extended nose to accommodate turbine power on these short-coupled, heavy-flying aircraft should be destabilizing. Let's find out how much! Extensive work (and detail!) on forming an appropriate mesh with adequate boundary layer.

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.

Aimed at incompressible external flow simulation of air around Ahmed Body.
