Simulation of pressurized liquid flow through orifice

Hello all,

 

do you have any tips or tutorials that will help to simulate dynamic flow analysis of liquid from the pressurized tank ? Lets say it can be Water or CO2 tank fielled in 2/3 with luquid and 1/3 with pressuriezed air

How to start with it and is it possible to do it with NX Flow?

Key task is to:

- check the predicted flow time and liquid flow rate (kg/s) through specific injector/nozzle

- check the discharge coefficient (CD) for specific injector/nozzle

- optionally to check the atomization characteristics of injector (when mixxing)

 

Anyone?
