Flow instabilities in open buoyant-thermocapillary pools
ORAL
Abstract
The flow structure in open buoyant-thermocapillary pools heated or cooled from above is investigated numerically. For pools of cylindrical shape and axisymmetric heat loads with a parabolic profile we carry out a systematic variation of the governing parameters such as the heating rate, Bond number, and the aspect ratio of the pool. The flow instability with respect to three-dimensional perturbations is is studied by a detailed analysis of the neutral modes.
