Thinning and Rupture of a Thin Liquid Film on a Horizontal Heated Solid Surface: Progress Report for Period June 16, 1987-July 31, 1988.

摘要

The analysis of the nonlinear stability and rupture of a thin liquid film on a heated horizontal plate has been completed. Extensions to condensing films, films subjected to constant heat fluxes and films with three-dimensional waves have been obtained. Multiple time scales were introduced in order to determine the effects of the initial conditions, and to clarify the behavior just before rupture. The general evolution equation has been derived for the case where both the viscosity and the surface tension are linear functions of temperature. The thinning and rupture of a thin film of an organic liquid on a non-uniformly heated Invar plate has been measured. Analysis of the data is in progress. 5 refs., 4 figs. (ERA citation 14:003337)
