surface tension (Marangoni effect) driven 2-phase flows
Posted: 10 Jun 2011, 14:34
Hello all,
I am interested in the opinion of users and developers as to whether it
is practical to use Elmer for a two-phase flow problem with the Marangoni effect. In this case, the Marangoni effect arises from the linear dependence of the surface tension on temperature.
The interface between the two phases (liquid and gas) deforms only slightly. Indeed as a first attempt, this interface could be fixed, with
only the shear stress (including the Marangoni effect) and tangential velocity (normal
velocity being zero) and temperature and normal heat flux matched there.
Cheers,
Frank
