Hello everyone

I have a model to atomize the fuel at the outlet holes( there are 18 holes on periphery)due to rotation(only) and i can't choose other particle break up models (like pressure atomization, orifice atomization). For a trial i chose water instead of fuel and hav run the vof multiphase (air-primary & water-2ndary) by keeping the BC's as

Wall-rotation (rpm is given)
Inlet-Velocity inlet
Outlet-Pressure outlet
Volume fraction of water at the inlet as 10%
and Back flow fraction- zero

I am not sure weather there'll b reversed flow though i am observing it. I can only see a film at the outlet but not particle break up. If you can understand the problem please give your suggestions if you could as i hav my deadlines coming..

sincerely, thanks in advance
regards
eers
