3D simulation

For the 3D simulation, two turbulent models were given to us : OES model and DDES k omega-SST model. 

Figure 2.2 – 3D Visualization with kw SST model

We have tested these two models to study the differences, the aim is to perform the 2D study on these 3D cases and follow the Kelvin-helmholtz structures.

We could represent the pressure coefficient around the second cylinder by using : 

Then, we can plot the pressure coefficient around the second cylinder compared with NASA results :
