TLDR
In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.About:

Metal Transfer and Arc Plasma in Gas Metal Arc Welding
J. Hu,Hai-Lung Tsai +1 more
TL;DR: In this paper, the transient complex heat transfer and fluid flow in molten metal and arc plasma during the gas metal arc welding process was analyzed and the model predicts the formation, growth, detachment, and transfer of droplets from the tip of a continuously fed electrode under the influences of several competing forces including gravity, electromagnetic force, arc pressure, plasma shear stress, and surface tension.
