Surface tension driven flow
 

Can anyone tell me how can I model a Surface tension driven flow?

Hi. Have you modeled a Surface tension driven flow. Because I also should model Surface tension driven flow for calculating Marangoni Number. But I do not know how to do it. Thanks.

Hi, Yes, I have modeled it. you must Use VOF method which is used for simulating multiphase flows. If u use Fluent u can choose each phase and enter interfacial tension between them and activate the adhision to wall. And in your walls Boundary conditions u can enter the contact angle between the fluids and the wall.

Kindly let me know the inlet and outlet boundary conditions you have used for your case.
