Abstract
Capillary open microsystems are increasingly used in biotechnology, biology, thermies and space science. Theory, numerics and applications of open microfluidics have considerably progressed during the last years. Two-phase capillary flow is however a field that still remains unexplored. In this early work, a theoretical basis for the spontaneous capillary two-phase flow in open channels is presented. A numerical investigation of the morphologies of plugs has been done using the Evolver software. Finally preliminary experimental results are presented.
