Does any one knw ..if a Nozzle modelling can be assumed to be a Laminar case ?( although Jet break up occuring inside is due to eddies and shear forces.)

Hi, I think you should use turbulent model for nozzle modeling/ It is one of classical task in CFD. If your nozzle has sharp edges (not rounded) there would be turbulent zone around nozzle under any velocity of stream in nozzle.
