Abstract Atomistic features of the Soret effect in multi-component systems, especially those in binary systems, are treated by the path probability method of irreversible statistical mechanics based on a rigid lattice model as an extension of our earlier treatment of the effect in one-component systems.

Kinetics of the Soret effect: Transient in the transport process
Physical Review A, 1990A Greens function is given for the canonical form of the thermodiffusion problem. The analytical and numerical solutions obtained for an initially homogeneous mixture reveal that the process at the boundaries is enhanced during the initial phase. This has to be related to the observations made by Tanner [Trans. Faraday Soc.

Large-scale convection induced by the Soret effect
Physical Review A, 1989We 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.

Soret Effect and Free Convection: A Way to Measure Soret Coefficients
2002The measurement of Soret coefficients is discussed in the frame of natural convection, both for Rayleigh-Benard and thermogravitational configurations. The Rayleigh-Benard configuration, together with the measurement of the Hopf frequency, is recommended for negative values of Soret coefficients; the record of the thermogravitational transient vertical

On the Cross-diffusion and Soret Effect in Multicomponent Mixtures
Microgravity Science and Technology, 2008The 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.

Long-wavelength thermocapillary instability with the Soret effect
Physical Review E, 2004We 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.

Effects of pH and temperature on the scanning Soret oximeter
Journal of Biomedical Engineering, 1993A 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, 2012A 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 ...
