Hi

I have been modelling underexpanded impinging jets issued from both convergent and de-Laval nozzles. I have assumed isentropic conditions at the nozzle exit (the computational domain excludes the nozzle interior). For some reason, the simulation is more accurate for the supersonic jet than the sonic jet. Any suggestions why this is the case?
