Converging Nozzle Ideal Ratios
Converging Nozzle Ideal Ratios
(OP)
Hi everyone,
I am new to the topics of compressible flow, and this question has been racking my brain for a while. Is there an ideal area ratio for a converging nozzle at which it no longer is beneficial to shrink the exit hole due to increased vortex growth and/or heat? This is all assuming speeds of around 0.4 mach. Thanks!

A0/A1 may be 1.2 / 1.3 (with gamma 1.4) and watching the back pressure to avoid Mach chocking as GregLocock said.
