Thermocapillary migration of two-dimensional, deformable, interacting bubbles toward an initially flat fluid interface in zero gravity is studied. The full Navier-Stokes equations and the thermal energy equation are solved for the fluids inside and outside the bubbles using a front tracking/finite difference method. The boundaries of the domain are taken to be periodic in the horizontal direction and wall-bounded in the vertical direction. The temperatures of the walls are fixed such that an upward temperature gradient is imposed. Interactions of coalescing bubbles with different initial conditions are investigated.
