Modeling of surface tension in fluidic MEMS using the level-set method

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A new numerical scheme for fluidic MEMS with gas and liquid mixture is developed in order to improve bubble or droplet-based microsystems. Key of the scheme for gas liquid two-phase flow is the modeling of surface tension force on the extremely thin interface between gas and liquid. This new scheme is successfully applied to simulate the thermocapillary motion of bubble in a microchannel by calculating the surface distribution accurately. Obtained results show good agreements with experimental data qualitatively. Several numerical assumptions required for micro fluidic systems especially near the channel wall are explained and differences with the conventional scheme are also discussed.
