surface tension in VOF

sharonyue · June 13, 2013, 20:44

hi guys,

As we know, the equations in VOF contain surface tension force. But I am confused about these functions. Anyone know how to deduce this equations straightly?

This might be as simple as you can get them. Are you familiar with the divergence and gradient operators?
