An experimental study of pattern formation in Be´nard-Marangoni convection with small aspect ratio containers
and high Prandtl number fluids is presented. The observed stationary patterns complete previous experimental
works performed at different values of aspect ratio and supercriticality. Detailed experimental
studies of the flow in some single structures are described, and spatial bifurcations between different stationary
planforms for a fixed aspect ratio are shown. These experimental results agree qualitatively with linear theory
analysis and with some previous numerical works about boundary conditions effects.
