So I guess you answer your own questions around here. I posted on Engineering Tips forum and had 5 positive responses in 24 hours. Here is a very helpful responce I recieved. Yes, what you are doing is possible. For air, the critical pressure is around 60% so for your 120 psig system, as...

I am wondering if I can use a shop air compressor (120psi) to achieve sonic flow? I am building a vortex tube (for spot cooling) and need a high velocity jet to form the vortex. What is the minimum pressure diff. required to achieve sonic flow of compressed air? Does varying the diameter of the...

Does no one see the beauty of the expansion chamber exuast?

You need an expansion chamber exhaust. It is truly magnificent invention. It consists of a convergant and divergent cone. The divergant cone causes a negative pressure on the exhaust sucking fuel/air mixture into the header. The convergant cone causes a positive pressure whith crams the fuel...
