Long-wavelength thermocapillary instability with the Soret effect

Physical Review E, 2004
We study the onset of Marangoni instability of the quiescent equilibrium in a binary liquid layer with a nondeformable interface in the presence of the Soret effect. Linear stability analysis shows that both monotonic and oscillatory long-wavelength instabilities are possible depending on the value of the Soret number chi.

The Soret effect in dry polymer electrolyte

Molecular Systems Design & Engineering, 2020
The Soret effect results in a concentration gradient when a mixture is exposed to a temperature gradient.

Large-scale convection induced by the Soret effect

Physical Review A, 1989
We present an experimental study of free convection in binary mixtures when convection is theoretically predicted to appear in the form of rolls of large extent. Quantitative measurements of the very slow velocities associated with this convective pattern are presented.

On the Cross-diffusion and Soret Effect in Multicomponent Mixtures

Microgravity Science and Technology, 2008
The model of convection in a multicomponent fluid is considered taking into account the cross-diffusion and the Soret effect. It is shown that the cross-diffusion coefficients can be eliminated by a linear change of composition and the thermal diffusion coefficients.

Electromigration and soret effect in cobalt

Solid State Communications, 1966
Abstract The present investigation aims to examine whether the electron-ion interaction in hole conductors follows the flow of charge carriers in electromigration experiments, as predicted by theory and observed in several electron conductors. Mass transport of cobalt, a hole conductor, under the influence of a direct current of about 10 4 A

The Soret effect in diffusion in crystals

Acta Materialia, 2008
Abstract The Soret effect, as it occurs in the diffusion of solutes in crystals, is analyzed using the principle of microscopic reversibility whereby an approach is developed for interpreting and computing Q ∗ , the heat of transport. To compute the transport of energy during the diffusion jump process, and then Q ∗ , the processes of thermal ...

Effects of pH and temperature on the scanning Soret oximeter

Journal of Biomedical Engineering, 1993
A new optical measurement technique based on spectral scanning (the scanning Soret oximeter) has previously been described. The technique has now been tested under extremes of physiological pH and temperature, the effects of which are shown to be negligible.

Driving forces and polymer hydrodynamics in the Soret effect

Journal of Physics: Condensed Matter, 2012
A temperature gradient induces different driving forces on the components of a mixture which translates into their segregation. We show that these driving forces constitute the physical picture behind the thermodiffusion effect, and provide an alternative expression of the Soret coefficient which can be applied to both colloidal suspensions and ...

Microscopic Interpretation of a Pure Chemical Contribution to the Soret Effect

Physical Review Letters, 2007
In a recent Letter by Köhler [Phys. Rev. Lett. 87, 055901 (2001)], it has been shown that the Soret effect or thermal diffusion can be split into three different contributions: mass, moment of inertia, and a so-called chemical effect, but only the chemical effect gives rise to a composition dependent contribution.
