Abstract
Dimensional analysis and similarity theory have been applied widely to physico-chemical hydrodynamics and related subjects, especially to heat and mass transfer theory. In this paper we study the movements of a drop, initially at rest. Because the drop is motionless, we introduced a viscous velocity U and a new dimensional number Ch. This approach permits us to evaluate the deformation and breakup of a drop, under surfactants adsorption, in dimensionless form.
