✦ Synopsis

Abstrwt-The

mechanism of the secondary liquid-liquid droplet-film rupture on an inclined plate has been examined theoretically and experimentally. A synergistic mixture, D2EHPA-TOPSkerosene, and phosphoric acid were used during the investigations. A fundamental approach has been used to aualyse a special stability and rupture problem of droplet-film structures during the secondary coalescence. In rupture adhesion processes, instead of viscous forces, some kind of electrical forces are supposed to be dominant. The stability and rupture problem of the secondary droplet-film structure on the inclined plate was analyzed using mechanical and electrical principles. Formation and rupture prooesses of the sexwndary liquid-liquid droplet-tibu structures were discussed considering the interfacial potential, its spontaneous and incident oscillations, impedance and impedance structure.
