title: Thermocapillary migration of bubbles: Convective effects at low Péclet number
review text: The authors examine the effect of weak convective heat transfer on the thermocapillary interaction of two bubbles migrating in an externally imposed temperature gradient. It is shown that equal-sized bubbles, which otherwise would move with equal velocities, acquire a relative motion apart from each other under the influence of convection. For slightly unequal bubbles, there are three different regimes of large-time asymptotic behaviour. Sufficient conditions for the realization of each regime are given in terms of Péclet number, initial separation and radii ratio.
