Shear-driven and channel flow of a liquid film over a corrugated or indented wall

The shape of the interface between two superimposed layers in a two-dimensional channel confined between a planar and a corrugated or indented wall is investigated in the limit of Stokes flow. A perturbation analysis for walls with small-amplitude sinusoidal corrugations reveals that an insoluble surfactant amplifies the deformation of the interface and causes a negative drift in the phase shif...

Ju l 2 00 7 Experimental studies of liquid - liquid dispersion in a turbulent shear flow

We study liquid-liquid dispersions in a turbulent Taylor–Couette flow, produced between two counterrotating coaxial cylinders. In pure Water and in counterrotation, Reynolds numbers up to 1.4× 10 are reached. The liquids we use are a low-viscous Oil and pure Water or a Sodium Iodide solution with a refractive index matched to that of Oil, in order to get transparent dispersions. We first charac...

Experimental studies of liquid-liquid dispersion in a turbulent shear flow

We built up an experiment to study liquid-liquid dispersions in a turbulent Taylor-Couette flow, produced between two counterrotating coaxial cylinders, of radii ri = 100mm and ro = 110mm (gap ratio η = ri/ro = 0.909). The useful length is L = 185mm. There is a space of 10mm between the cylinders bottom ends and a free surface on the top. The cylinders rotation rates ωi and ωo can be set indepe...

Influences of Interfacial Shear in Turbulent Film Boiling on a Horizontal Tube with External Flowing Liquid

The paper presents a theoretical study about turbulent film boiling on a horizontal tube with external flowing liquid. The high velocity flowing liquid is determined by potential flow theory. By using Colburn analogy, the present paper successfully addresses a new model to predict the vaporliquid interfacial shear, applies the interfacial shear into the forced balance equation and then combines...

Chaotic dynamos generated by a turbulent flow of liquid sodium.

We report the observation of several dynamical regimes of the magnetic field generated by a turbulent flow of liquid sodium (VKS experiment). Stationary dynamos, transitions to relaxation cycles or to intermittent bursts, and random field reversals occur in a fairly small range of parameters. Large scale dynamics of the magnetic field result from the interactions of a few modes. The low dimensi...
