✦ Synopsis

A process of nonlinear three-dimensional rupture of thin liquid films is numerically analyzed for the first time. With the rupture time being successfully calculated, it has been possible to develop a more complete rupture theory for thin liquid films. In contrast to the linear analysis indicating the shortest rupture time of thin liquid films to be the same for both two- and three-dimensional rupture, the nonlinear analysis reveals that the latter proceeds faster than the former. In particular, among all three-dimensional disturbance modes, the symmetric one makes the thin liquid films rupture fastest. It is concluded that the rupture process develops at a point rather than along a line on thin liquid films.

Effects of electromagnetic retardation on the rupture process of a very thin liquid film coated on a flat plate are studied. The analysis results indicate that the electromagnetic retardation effect (D) for the case A > 0 (attraction) is a stabilization factor, which prolongs the rupture time. The w
