What is it about?
This paper explains the methodology applied to design a new facility at VKI to perform PIV and acoustics measurements on a supersonic coaxial jet.

Why is it important?
Commercial turbofan engines usually operates at cruise in supersonic underexpanded condition. This is source of a huge portion of the cabin noise. Few studies have been conducted on supersonic coaxial jet aeroacoustics so far. This is the first example of PIV applied to supersonic coaxial flow.
Perspectives
This is just a preliminary step in order to present to the scientific community the new facility. Others publications will follow showing the results of the acoustic and PIV investigation on a supersonic coaxial jet.
