Physico-chemical hydrodynamics

English : these works mainly focused on the coupling between thermocapillary and thermogravitational convections. The use of binary alcohol systems presenting unusual dependences of the interfacial or surface tension allowed the study of both positive and negative coupling of the bulk and capillary convections. Some more occasional works have been done on limited studies, like convection implying thermodiffusion (Soret effect), Laser Doppler Velocimetry (LDV), and numerical developments of finite differences algorithms applied to natural convection problems.

Français : ces travaux sont concentrés sur le couplage entre les convections capillaire et thermogravitationnelle. L’utilisation de systèmes présentant une variation inhabituelle de la tension superficielle ou interfaciale a permis l’étude de couplages positif et négatif. Quelques publications concernent des activités plus ponctuelles, tels que la convection avec thermodiffusion, la vélocimétrie laser-Doppler, le développement et l’évaluation d’algorithmes de différences finies appliqués à ces problèmes.
