TEARING SEPARATION OF VISCOUS FLUID LAYERS UNDER SURFACE TENSION MEMBRANE BOUNDARIES.

Abstract

The slow flow of a viscous fluid is examined when a layer of fluid branches, or is torn, about a surface tension membrane. The solution of this flow requires the determination of the position of the surface tension membrane. The report describes a numerical method which is used to solve the flow between two counter-rotating rollers which are partially immersed in a large bath of viscous fluid. The results obtained are in close agreement with the available experimental evidence. These results are applied to a closely related problem in which two flexible tapes, bonded by a layer of viscous adhesive, are peeled apart around cylindrical guides. A simplified analytical model is also examined in which a 'knife edge' placed between the rollers induces separation of the viscous layer. (Author)
