Linearly Unstable Modes on the Membrane Approximation to an Annular Liquid Sheet

Journal of the Physical Society of Japan, 2004
It is shown in the linear analysis that an annular liquid sheet becomes unstable for long wave axisymmetric disturbances on the sheet, while stable for non-axisymmetric disturbances in the absence of swirl. Furthermore, for large deformation and breakup process of the sheet, the nonlinear analysis has been made by several investigators.

Preparation of annular hollow fibre membranes

Additives for Polymers, 2000
Abstract Preparation of an annular hollow fibre membrane using a triple-orifice spinneret was studied. Various annular hollow fibre membranes were prepared from different membrane forming systems. The polymers used in spinning the annular hollow fibres include polysulfone (PSf), polyethersulfone (PESf), polyetherimide (PEI) and cellulose acetate ...

FINITE PLANE TWIST OF AN ANNULAR MEMBRANE

The Quarterly Journal of Mechanics and Applied Mathematics, 1993
Summary: We present an analysis of the finite deformation of an annular membrane induced by the rotation of a rigid hub. The membrane is partly wrinkled for certain combinations of hub radius and rotation angle. For a particular strain-energy function of harmonic type, we obtain solutions that are analytical in the sense that the problem is reduced to ...

Oscillating annular liquid membranes

Archive of Applied Mechanics, 1992
The response of annular liquid membranes to sinusoidal mass flow rate fluctuations at the nozzle exit is analyzed as a function of the amplitude and frequency of the axial velocity fluctuations at the nozzle exit and thermodynamic compression of the gas enclosed by the membrane.

Electroactive liquid lens driven by an annular membrane

Optics Letters, 2014
Unlike traditional focalization that recruits multiple moving lens elements to adjust focus, liquid lenses deliver adaptive focusing by simply tuning the surface profile of liquid or the elastomer that encloses liquid. Its simple and compact configuration, low cost, and actuation efficiency promise wide industrial, medical, and consumer applications ...

The Annular Membrane Under Axial Load

Journal of Applied Mechanics, 1981
An exact solution is given of the nonlinear differential equations for the large deflection behavior of an initially unstressed annular membrane under axial load for the case of Poisson’s ratio equal to one third.

Analysis of Annular Liquid Membranes and Their Singularities

Meccanica, 1997
The singularities of the equations governing the dynamics of steady axisymmetric annular liquid membranes subject to gravity are analyzed by means of two different formulations based on the membrane mean radius and mass per unit length, and on the axial and radial velocity components, respectively.

Elastic, Large Deflections of Annular Membranes

Journal of the Engineering Mechanics Division, 1966
In studying various problems arising in the analysis of radially symmetric membranes, existing theories are investigated under the boundary conditions (1) simple continuous circular membrane, uniformly loaded and (2) pressure loaded membrane additionally loaded by an opposing force centrally applied through a smaller disc rigidly cemented to the ...

Involutes: the geometry of chemical waves rotating in annular membranes

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1995
According to earlier theories certain parts of a chemical wave front propagating in a 2-D excitable medium with a convex obstacle should be involutes of that obstacle. The present paper discusses a special case where self-sustained chemical waves are rotating around a central obstacle in an annular 2-D excitable region.
