I am simulating 2D (also 3D) pipe flow using VOF. Results are good if I don't activate surface tension and wall adhesion. But in order to know the surface tension and wall adhesion (contact angle given) effects I activated those, but the results what I am getting are very un-physical. What could be the reason?

PS: Experimental results are in good agreement with what we expected with the contact angle and surface tension.
