Turbulent Round Jet CFD Analysis with SU2 Code: from Validation to Aircraft's Exhaust.

Computational Fluid Dynamics is getting more and more an established reality in nowadays engineering applications involving uids. Being able to simulate uids' behavior in di erent con gurations is an incredibly strong tool for many engineering elds varying from components' design to climatic e ects' estimations. A lot of research is currently based on using CFD software to obtain results in a faster, easier and less expensive way, compared to reproducing the uids behavior in experiments. This is why it becomes very interesting understanding what tools are available, what is their current status, how to better exploit them. There are already some well-established CFD codes that are widely adopted and that have been intensively developed during the years, but most of them are really expensive. The rst aim of this work is to evaluate SU2, a new open-source (free) CFD code developed by Stanford University, in the speci c con guration of turbulent round jets. This tool already shows incredible capability and it has been used with success in a wide range of other cases. My intent was to give my contribution by testing the software in such con guration. The idea is to show potential new users how to better adjust the settings to obtain reliable results, but also to give a feedback to the software developers on possible improvements to be performed on the code. Second aim is to provide a wide range of results when dealing with turbulent round jets with the ultimate goal to get as close as possible to precisely simulate a general aircraft's exhaust uid ow.
