Hi, I would like to impleme
I would like to implement a boundary condition for thermocapillary convection. Pardon my ignorance - but I am wondering if (what..) difference it would make if I consider it a momentum source somehow like
with T=Temperature, z =coordinate parallel to surface, A=area of a surface element, dG/dT dependency of surface tension on temperature, and V = Volume of the volume cell adjacent to the surface element
or as a fixed gradient condition:
mu=viscosity, dU/dn velocity gradient perpendicular to surface
Thank you very much for any hint !
