This paper is an attempt to study the effects of surface topography on the flow of a droplet (or
a bubble) in a low Reynolds number flow regime. Multiphase flows through a constricted …

Fully resolved numerical simulations are used to examine the thermocapillary motion of a
two-and three-dimensional fully deformable bubble in a channel with an obstruction. A front …

Pressure-driven droplet flows through a straight channel are mainly governed by viscous
and interfacial forces. The droplet either attains a steady shape, undergoes breakup or …

We numerically investigate the deformation of a train of power-law droplets in a highly
viscous suspending medium in nonlinear microfluidic geometry. We examine how viscous …

We experimentally investigate the interaction between individual bubble deformations and
collective distortions of segmented flows in nonlinear microfluidic geometries. Using highly …
