Marangoni convection in V-shaped containers

This paper presents a numerical study of the time evolution of Marangoni convection in two V-shaped containers involved in the microgravity experiments reported earlier. First the case of the triangular container with a plane gas/liquid interface is considered, next the container having the shape of a circular sector with a curved interface is dealt with. The numerical results show the same behaviour as observed experimentally: convection caused by macroscale effects in the former, and microconvection in the latter case.
