摘要

We have used a holographic interferometry device to perform an investigation of the interdiffusion coefficient and the Soret coefficient of the concentrated aqueous elestrolyte(LiCl; 9,7H_2O), free from any convective disturbance. The influence of the concentration gradient induced by the thermal diffusion on the hydrodynamic behaviour in a confined geometry has also been checked, thanks to the high viscosity of the mixture. We study the evolution of the first instability threshold and of the convection pattern and compare them to the literature results in the Rayleigh-Benard geometry.
