โœฆ Synopsis

This paper utilizes a computational approach to address the effect of bubble deformation on the transient thermocapillary migration of bubbles in a microgravitational environment. We use a finite volume method with interface tracking capability on a moving unstructured mesh. We consider a range of Reynolds and Marangoni numbers from 1 to 100 and a range of capillary numbers from 0.001 to 0.1. The transient migration of bubbles in which bubble deformation is significant is described.

The axisymmetric motion and deformation of two viscous drops to high temperature regions due to the variation of interfacial in a temperature field with an imposed gradient along their line tension that is usually a decreasing function of increasing of centers are considered. When heat convection an
