Nozzle Flow Simulation
 

Dear,

Actually, I'm pretty new with the simulation by using CFX and would like some kind of suggestion which can help me to start this correctly.

My problem is the nozzle jet which will spray Nitrogen on to target at the height of a few hundred micron. Therefore, I would like to simulation the flow effect which probably mass flow or pressure over my target to evaluate my nozzle design.

I'd start from my nozzle with 2 domains and both domain has different fluid property. Anyway, please kindly comment the I can start it up correctly and Thank you so much indeed.
