Thermodiffusocapillary flows in a twodimensional rectangular cavity
Abstract
Thermodiffusocapillary flows in a twodimensional rectangular cavity are numerically investigated. The side walls of the cavity are maintained at constant but different values of temperature and concentration. The induced thermocapillary and diffusocapillary forces may augment or oppose each other. The results indicate that, when these two capillary forces augment each other, the fluid system assumes a singlecellular motion. When they oppose each other, depending on the magnitudes of Marangoni number Ma, Lewis number Le, and surfacetension ratio gamma, the fluid system may be quiescent or assumes a singlecellular, a doublecellular, or a tripplecellular motion. Furthermore, for a fixed value of Ma and a smaller value of gamma, it needs a larger value of Le to render a multiplecell flow structure.
