The flow in two liquids inside a rectangular side-heated cavity, driven by a thermal-gradient-induced Marangoni effect along the common interface, is investigated numerically using molecular dynamics simulations. For this configuration the surface-tension gradient drives two counter-rotating vortices inside the cavity. The model fluids are simple Lennard-Jones type fluids, selected for varying liquid-solid contact angles. The velocity field is determined and compared to analytical results of the continuum creeping-flow approximation of this configuration.
