ANANALYSIS OF THE LIGAMENT-TYPE DISINTEGRATION OF THIN LIQUID FILM AT THE EDGE OF A ROTATING DISK

An analysis of ligament-type disintegration was made by equating the rate of dissipation of kinetic energy, surface energy and viscous deformation energy of disturbance of the liquid film to the motive power by centrifugal force at the edge of a rotating disk. The number of ligaments generated in disintegration of liquid film is given as a function of the Weber number and the stability number. This analysis gives an interpretation on the basis of the energy balance for the experimental results by Hinze and his co-worker, who used a rotating cup and represented the same expression as the present paper.
