Thermocapillary bubble migration—thermal boundary layers for large Marangoni numbers

TLDR
In this paper, the migration of an isolated gas bubble in an immiscible liquid possessing a temperature gradient is analyzed in the absence of gravity, where the driving force for the bubble motion is the shear stress at the interface which is a consequence of the temperature dependence of the surface tension.

Thermocapillary motion of deformable drops at finite Reynolds and Marangoni numbers

TL;DR: In this article, the authors present the results of numerical simulations of the three-dimensional thermocapillary motion of deformable viscous drops under the influence of a constant temperature gradient within a second liquid medium and examine the effects of shape deformations and convective transport of momentum and energy on the migration velocity of the drop.

The migration of a drop in a uniform temperature gradient at large Marangoni numbers

TL;DR: In this paper, the authors considered the steady thermocapillary motion of a spherical drop in a uniform temperature gradient, where convective transport of energy is predominant in the drop phase as well as in the continuous phase.

The motion of bubbles in a vertical temperature gradient

TL;DR: In this article, it has been demonstrated that small bubbles in pure liquids can be held stationary or driven downwards by means of a sufficiently strong negative temperature gradient in the vertical direction, due to the stresses resulting from the thermal variation of surface tension at the bubble surface.
