摘要

This chapter introduces examples of thermocapillary-driven flows and resultant phenomena in the liquid bridges under microgravity conditions and/or in microscale in spatial dimensions. In the first section, a unique phenomenon by tiny particles suspended in the half-zone liquid bridges, known as ‘particle accumulation structures (PASs)’ is introduced. The second section describes the effect of thermocapillary-flow on the pinching of the liquid bridges. In the third section, an application of the liquid-bridge pinching for the formation of nano-liter droplet is presented.
