Convection in Binary Liquids with Soret Effect: What We Can Learn from Laser Doppler Velocimetry Exp coupling between the temperature and the concentration fields (since a more recent review does not exist, see e.g. Platten & Legros 1984). For example, the oscillatory onset of convection was not only theoretically predicted almost 20 years ago (Platten 1971 — Shteinberg 1971 — Hurle & Jakeman 1971

Boundary Layer Analysis of Traveling Waves in Binary Convection been found experimentally.. The situation is very different from what happens in pure fluid convection, due to the fact that the conducting state gets destabilized at a finite frequency through a Hopf bifurcation.. Propagative rolls are often observed, bifurcating subcritically when the control par

Structure and Dynamics of Nonlinear Convective States in Binary Fluid Mixturess numerical solutions of the basic hydrodynamic field equations subject to realistic horizontal boundary conditions. Bifurcation— and phase diagrams for TW and SOC solutions are presented. Unstable SOC patterns that decay into a stable TW or the conductive state can be stabilized by phase pinning la

Recently one of us has shown. for a layer in an external concentration gradient that the onset of convection is significantly influenced by the different physical properties of liquid and gas mixtures:

Experimental Study of Binary Fluid Convection in a Quasi 1-Dimensional Cell without Reflections fromto distinguish between a convectively unstable and an absolutely unstable situation. We present an observation in a cell where the fluid becomes unstable at the absolute instability point, not at the convective one as in most other experiments. This is done by preventing the sides of the cell from r

In a range of speeds where the water is Taylor unstable and the oil Taylor stable, we get strange Taylor cells of emulsified fluids whose length may be three or even four times larger than normal. The length of cells appears to

An exact agreement is found with the borders of the Busse balloon, concerning the long wavelength instabilities. We propose a calculation of the selected wavenumber which agrees closely with experiments and we predict a new instability which appears to be important in initiating time d
