Thermocapillary motion of deformable drops and bubbles
نویسندگان
چکیده
In this paper we report on a numerical method to include Marangoni forces into a finitevolume solver for multi-phase flows. Our work is motivated by the question of whether thermal fluctuations typically found in combustion applications can impact the atomization of fuel drops due to variations in surface tension. To verify and validate our proposed method, we compare our results to theoretically predicted thermocapillary migration velocities of drops and to experimentally measured migration velocities in micro-gravity environments.

On the thermocapillary motion of deformable droplets
In studies on Marangoni type motion of particles the surface tension is often approximated as a linear function of temperature. For deformable particles in a linear external temperature gradient far from the reference point this approximation yields a negative surface tension which is physically unrealistic. It is shown that H. Zhou and R. H. Davis (J. Colloid Interface Sci., 181, 60, (1996)) p...

متن کاملSurfactant effects on thermocapillary interactions of deformable drops.
A three-dimensional boundary-integral algorithm is used to study thermocapillary interactions of two deformable drops in the presence of bulk-insoluble, non-ionic surfactant. The primary effect of deformation is to slow down the rate of film drainage between drops in close approach and prevent coalescence in the absence of van der Waals forces. Both linear and non-linear models are used to desc...

In this paper, simulations are performed of the thermocapillary motion of three-dimensional and axisymmetric drops in a confined apparatus. The refined level-set grid method is used to track the interface and resolve very small deformations. We compare our results to theoretically predicted thermocapillary migration velocities of drops and to experimentally measured migration velocities in micr...
متن کاملPlanar thermocapillary migration of two bubbles in microgravity environment
A theoretical investigation is performed on the thermocapillary motion of two bubbles in arbitrary configuration in microgravity environment under the assumption that the surface tension is high enough to keep the bubbles spherical. The two bubbles are driven by the surface tension gradient due to temperature nonuniformity on the surfaces. The bubble interaction is considered for the limit of s...
