Abstract
This isapioneeringpaperthatdealswiththesemi-steady-stateliquidfilmthicknessonarotatingdrum
partially submergedinliquidusingCFD.TheCFDpredictionshavebeencomparedwithbothexperimental
results andanalyticalsolutions.Theliquidfilmthicknessandthefilmrisingonacircularcurvedwall
were monitoredforvariousrpmoftherotatingdrum.The2Dsimulationswereperformedneglectingthe
end effects(assumingtherotatingdrumisverylong).Astherotatingdrumspeedwasincreased,thefilm
thickness wasfoundtoincreaseatthefilmrisingsideandattheminimumfilmthicknesspoint(topof
the rotatingdrum).Therewasneverbeenasteady-stateconditionreached,theoppositewasexpected

to keepthelevelofthefreesurfaceconstant.
