Lubrication theory is employed to examine surface-tension-dominated flows that arise during the application of thin coatings, using pressurized dies, to axially symmetric fibres. In all cases, it is assumed that the clearance between the die exit and

Aerosol droplets in monodisperse sprays produced by spinning disc generators are shown to correlate with a simple law when the controlling parameters are represented in an appropriate dimensionless form. This correlation holds for liquids of widely d

Entrapment of small air bubbles is a problem for continuous liquid-film coatings processes. The coating of any surface requires that the surrounding air in contact with it be displaced by an advancing liquid interface. Studies of dynamic wetting sugg

The phenomenon colloquially known as a fiber fuse occurs when an optical fiber carrying high power is damaged or in some way abused. Beginning at the damage site a brilliant, highly visible plasmalike disturbance propagates back toward the optical so

Quantitative velocity measurements of unsteady convection in a Bénard cell suddenly cooled from above to a supercritical Rayleigh number are reported. The results are obtained by a novel application of laser speckle photography adapted for the study

Caustics created by internal reflections and interface refraction have been observed in the molten drawdown zones of fibers during manufacture in a laser furnace. These regions of high luminescence are associated with the rapid change in cross-sectio

New observations of the convective states in a vertical slot in the neighborhood of the transition to multicellular motion are reported. Experiments in large Prandtl number fluids reveal that the departure from unicellular flow develops gradually in

Cavity flows driven by an applied horizontal temperature gradient are encountered in a variety of industrial and environmental situations. Determination of the core structure, away from the flow boundaries, depends strongly on the corner behaviour of
