modeling gas expansion

hi, this is the first time I use FLUENT because I need to simulate a gas jet coming out of a very small nozzle into vacuum. e.g. the density profile or pressure distribution (not the flow inside the nozzle). Assuming I know the mass flow rate at the nozzle tip.
It seems to be a not so tricky problem but I just can't make the correct boundary conditions or models to get convergence or physical results.  Can anyone please help and give me some suggestions? I'll be very appreciative. |
