Pattern dynamics in a Bénard-Marangoni convection experiment

In this paper we report a Bénard-Marangoni convection experiment in a small aspect ratio square cell, at a high Rayleigh number. In the time dependent convection regime, low dimensional chaotic behaviour is identified for a variable measured from the pattern. A dynamical system is proposed to model...
