Moving contact line on solid object, OpenFoam
 

Hi All,

I don't know too much about OpenFoam and I need to ask a general question.

I know OpenFoam can solve multiphase problems, the problem under my consideration is a moving solid object through a fluid-fluid interface.

I need to define the contact angle when there is a fluid-fluid-solid contact line an this contact line may be moving as the solid is moving.

I just want to know if OpenFoam can solve this problem before making any decisions to learn using it. I tried this problem in Gerris but turns out Gerris doesn't solve this kind of problem.

Thank you for all your suggestions!

Best,

Well, without more detail about what kind of physics you require on the moving solid I am not sure how much work it will require on your part. There are solvers which can handle two-phase flow with a sharp fluid-fluid interface and a moving boundary. Check out the various tutorial cases for interDyMFoam. Hope that points you in the right direction.

Thank you for your reply!

Actually I think the problem is simple. I just want to simulate a solid ball falling through a fluid interface and I believe a solver that deals with a sharp interface and moving contact line will be very helpful.

Thanks for your suggestions!
