gunvirs New Member gsingh Join Date: Jul 2016 Posts: 1 Rep Power: 0	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.
