Mach number -- CFD Online Discussion Forums

July 2, 2008, 10:51	Mach number	#1
Singh Guest Posts: n/a	I am given the Chamber, jet exit and ambient conditions (pressure and temperature). I needed clarification on the definition of Mach number if Mj = sqrt ((2/(gamma -1)) *[(po/pa)^(gamma/gamma-1)-1]) Basically the Isentropic Mach number. How do I calculate the Mach number at the nozzle exit plane? Secondly, I would appreciate it if anyone could please point out some references for sonic and supersonic nozzle profiles. I need the correct nozzle geometry data for grid generation. Thanks a lot.
