Could the current machines be utilizing their - ready availability of compressed air - for an alternative method?:
Great minds think alike.
I was looking at the likelyhood of this device being used in the Ferrari, but there is a problem of efficiency.
You use kinetic energy of the air to make a vortex, the centre of the vortex creates an expansion zone and some of that air from that voretex sucked into the zone where it is cools.
The main flow in the outer voretx is rejected with at a higher temperature. Now how much heat is this to cool?
The central vortext is ejected at a colder temperature... Now how much cooling can this provide?
How much additional compressor work is used to drive the vortex cooler? And how much addition pressure and temperature load does this put on the compressor?
The design must be according to the rules. All air from the compressor must exit through the turbine. A design could be like this:
You take the cool bleed off air from the vortex cooler and send it back inside the compressor or to a charger cooler.
For the hot exhaust air from the vortex cooler you dump this into the exhaust header. How much will this cool the exhaust gas? It is bad if it cools it too much.
Even though I haven't done any calculations I will go out on a limb and say this is too inefficient to work.
