drop on a vibrating surface
 
Dear all,

I am trying to model a droplet (say water) on a vibrating surface. For the surface I am using dynamicInkJetFvMesh and interDyMFoam solver. I have some doubts.

Droplet slips off the surface after some time. BC that I gave at the vib surface are the zero gradient for alpha and P_rgh and movingWallVelocity for U. Can anybody tell me if I need to incorporate some kind of friction between drop and surface ? And if so then how can that be implemented.


Secondly, a droplet on a surface is not perfectly hemispherical. So far I was using sphereToCell for it but I think its better if i could specify the contact angles. I dont know exactly how changes in contact angles are implemented in interDyMFoam.

Sry for such trivial questions.. Still hope for some reply..


Regards
