In my problem a round axisymmetric air jet issuing in quiescent air is considered.The flow is of a constant density.
Jet dia is 15 mm , velocity 100 m/s , Re=95500
please help me in simulating this case in Openfoam .
Which BC, solver to use?
Also suggest which turbulence model to be used?

i have tried simulating it but the jet is decaying very early and its not spreading as it should.
So far i've used PisoFoam and Simplefoam.
