Instabilities of Waves on a Free Surface
Studies in Applied Mathematics, 1986This paper is concerned with instabilities which develop on a class of parallel shear flows in the presence of a free surface. Implicit in this type of study is the existence of three dimensional instabilities on slightly perturbed two dimensional spatially periodic shear flows.

Coloring Triangle-Free Graphs on Surfaces
Proceedings of the Twentieth Annual ACM-SIAM Symposium on Discrete Algorithms, 2007We are concerned with coloring graphs that embed in a fixed surface. This restriction often makes coloring problems tractable, and the purpose of this abstract is to describe a new result along these lines.

Free- and near-free-surface swirling turbulent jets
AIAA Journal, 1998he turbulent flowfield created by a round swirling jet issuing from a nozzle, beneath and parallel to a free surface, in both the deep- and shallow-submergence modes has been studied for three swirl numbers (S = 0.265, 0.500, and 0.522) and fixed Froude and Reynolds numbers using a three-component laser Doppler velocimetry system.

Free-surface flow of hyperconcentrations
Fluid Dynamics Research, 1999Summary: A mixture of fluid and solid particles with high sediment concentration (hyperconcentration) is described by a non-Newtonian rheological model incorporating the yield stress, a linear (viscous) stress, and a quadratic (turbulent-dispersive) term.

Surface Free Energy. Surface Tension
1993The surface tension γ and the (specific) surface free energy σ of a crystal face with area A are related by γ = σ+ A•(dσ/dA) [1]. There is some confusion in the literature in properly using γ and σ; for a more recent discussion of the difference between σ and γ, see [2 to 4].

On the wrinkling of a free surface
Journal of Applied Physics, 1977We consider an elastic half-space whose free surface is capable of supporting its own stress field. This stress is a linear function of surface strain and is related to the stress in the interior of the body by a nonclassical boundary condition. We study the wrinkling (buckling) of the surface and show that this type of behavior is possible whenever ...

Cubulating surface‐by‐free groups
Journal of TopologyAbstractLet be an exact sequence where is the fundamental group of a closed surface of genus greater than one, is hyperbolic, and is finitely generated free. The aim of this paper is to provide sufficient conditions to prove that is cubulable and construct examples satisfying these conditions.

Cusp shapes are widely observed in nature, most famously as the bright caustic lines on the inside of a coffee cup. This can be understood from the fact that a cusp arises from the smooth deformation of a parameterized curve. Remarkably, the same generic cusp can be formed on the surface of a viscous fluid with surface tension, as demonstrated by Jeong

A dislocation at a free surface
Philosophical Magazine, 1961Abstract The stress field of a dislocation meeting a free surface of an elastic body is calculated for any angle of incidence and any Burgers vector.
