Instability of Liquid Surfaces and the Formation of Drops

Journal of Applied Physics, 1954
The theory of Taylor instability is extended to take account of surface tension, and the most unstable mode is determined. The resulting theory is then used to estimate the size of drops which might be formed as a result of this instability.

Instabilities of Surface Waves

1995
Low-temperature plasmas have been of much interest recently because of their usefulness in many technological applications of plasmas for which very high temperatures such as those in fusion plasmas are not required. Unlike hot plasmas, which must be confined by strong magnetic fields, most low-temperature laboratory plasmas are bounded by rigid ...

Cracklike surface instabilities in stressed solids

Physical Review Letters, 1993
The surface of an elastically stressed solid is shown to undergo an instability in which deep, cracklike grooves form by surface diffusion. These grooves sharpen and accelerate as they deepen. The resultant morphology is in excellent agreement with recent experimental observation in several disparate materials systems.

Taylor instability of finite surface waves

Journal of Fluid Mechanics, 1960
The instability of the accelerated interface between a liquid (methanol or carbon tetrachloride) and air has been investigated experimentally for approximate sinusoidal disturbances of wave-number range from well below to well above the cut-off. The growth rates are measured and compared with theoretical results.

INSTABILITY OF PLANING SURFACES

1969
Abstract : A mathematical analysis is developed for the hydrodynamic problem of a two-dimensional planing surface which is heaving sinusoidally. From the assumptions of small angle of attack and small amplitudes of motion, it is possible to formulate a linear problem. Gravity is neglected.

Instabilities and Surface Tension

1988
I shall present below recent progress made in the study of the effect of surface tension on various instabilities. The attention will be on two well known physical phenomena: Saffman-Taylor fingers in long rectangular channels and needle crystals growing at the expanse of a supercooled melt.

Surface instability of a gel disc in swelling

The European Physical Journal E, 2013
The swelling of a soft disc made of polymeric gel and attached to a fixed substrate is modeled using a variational method in nonlinear elasticity. A linear stability analysis is performed to detect the onset of a surface instability. An exact solution of the perturbed disc is found, and both the threshold values of the growth rates and the surface ...
