VOF,Multiphase modeling

Mavinakere

Hi all,I've been recently working on multiphase phase modeling of air and water around a automobile tire.I ran some 3D calculations for the domain 50mm from the ground and 370mm wide.Water is 8mm hegh and rest till top 50mm is air.I used K-E, RNG to get solutions.Well, when i compared my results with the abstract paper i had...the pressure values seems to match but not the force values...i'm getting the lift and drag forces approximately 10 times more than the obtained values in the paper.Can anybody please throw some light on my problem? Thanks in advance.Mavinakere.
