Stalactite growth as a free-boundary problem

  title={Stalactite growth as a free-boundary problem},
  author={M. Short and J. Baygents and R. Goldstein},
Stalactites, the most familiar structures found hanging from the ceilings of limestone caves, grow by the precipitation of calcium carbonate from within a thin film of fluid flowing down their surfaces. We have recently shown [M. B. Short, J. C. Baygents, J. W. Beck, D. A. Stone, R. S. Toomey III, and R. E. Goldstein, “Stalactite growth as a free-boundary problem: A geometric law and its Platonic ideal,” Phys. Rev. Lett. 94, 018501 (2005)] that the combination of thin-film fluid dynamics… Expand
Fluids, form, and function: The role of fluid dynamics in the evolution of stalactites, icicles, and aquatic microorganisms
This dissertation is devoted to better understandin g the role that fluids play in the selection of the shapes and functions of objects and cre atu s in nature. Toward that end, three specificExpand
Thin-film-induced morphological instabilities over calcite surfaces
The marginal role played by carbon dioxide transport in generating crenulation patterns, which are indeed induced by the hydrodynamic response of the free surface of the water film, is demonstrated. Expand
A free-boundary theory for the shape of the ideal dripping icicle
The growth of icicles is considered as a free-boundary problem. A synthesis of atmospheric heat transfer, geometrical considerations, and thin-film fluid dynamics leads to a nonlinear ordinaryExpand
Morphological attractors in natural convective dissolution
Recent experiments demonstrate how a soluble body placed in a fluid spontaneously forms a dissolution pinnacle — a slender, upward pointing shape that resembles naturally occurring karst pinnaclesExpand
An asymptotic approach to the crenulation instability
A novel linear stability analysis for the pattern formation of ripple-like corrugations, over the surface of stalactites due to calcite-laden falling films, is presented by using a modified versionExpand
The hydrodynamic genesis of linear karren patterns
Abstract In karst and alpine areas, the interactions between water and rocks give rise to a large variety of marvellous patterns. In this work, we provide a hydrodynamic model for the formation ofExpand
Instability and dripping of electrified liquid films flowing down inverted substrates
We consider the gravity-driven flow of a perfect dielectric, viscous, thin liquid film, wetting a flat substrate inclined at a non-zero angle to the horizontal. The dynamics of the thin film isExpand
Steady states and linear stability analysis of precipitation pattern formation at geothermal hot springs.
A dynamical theory of geophysical precipitation pattern formation is presented and applied to irreversible calcium carbonate (travertine) deposition and a linear instability that underlies scale-invariant travertine terrace formation at geothermal hot springs is identified. Expand
Do dissolving objects converge to a universal shape?
This work investigates the shape of dissolving cylinders in a large volume of water and suggests that this paraboloidal shape is the geometric attractor for the dissolution of noncrystalline objects in the presence of gravity. Expand
Hydrodynamic-driven morphogenesis of karst draperies: spatio-temporal analysis of the two-dimensional impulse response
Abstract We study the role of hydrodynamic instabilities in the morphogenesis of some typical karst draperies structures encountered in limestone caves. The problem is tackled using the long waveExpand


Stalactite growth as a free-boundary problem: a geometric law and its platonic ideal.
The interplay of thin-film fluid dynamics, calcium carbonate chemistry, and CO2 transport in the cave is considered to show that stalactites evolve according to a novel local geometric growth law which exhibits extreme amplification at the tip as a consequence of the locally-varying fluid layer thickness.

It is found that restoring forces due to gravity and surface tension is an important factor for stabilization of the solid-liquid interface on long length scales. Expand

Stalagmite growth and palaeo-climate: the numerical perspective
Abstract The growth of stalagmites can be approximated by a simple mathematical model, which depends on growth rate and equilibrium radius. These two parameters are controlled by the climate.Expand

Abstract A variety of non-equilibrium growth processes are characterized by phase boundaries consisting of moving fingers, often with interesting secondary structures such as sidebranches. FamiliarExpand

This work reports a self-organized periodic templating mechanism producing tubular structures electrochemically in iron-ammonium-sulfate solutions; iron oxides precipitate on the surface of bubbles that linger at the tube rim and then detach, leaving behind a ring of material. Expand
Chemical kinetics, speleothem growth and climate
The morphology and stratigraphy of speleothems are controlled by parameters that depend on climate. These are the water supply rates feeding the speleothem, e.g. a stalagmite, the growth ratesExpand
Geometrical models of interface evolution
We introduce a class of models for the motion of a boundary between time-dependent phase domains in which the interface itself satisfies an equation of motion. The intended application is to systemsExpand

This paper shows that quantitatively unexplained stationary waves or ridges often encircle icicles are caused by a quite different type of surface instability related to thermal diffusion and the hydrodynamic effect of a thin water flow. Expand
