Abstract:

Basic concepts and principles of volume of fluid（VOF）in computational fluid dynamics（CFD）are briefly introduced. Current progress in modeling of velocity fields，generation and development of bubbles or microdroplets，impacts of film thickness near the wall，mass and heat transfer performance of Taylor flow in microchannels are summarized. Future research trends and application of CFD numerical study in microchannel are further discussed.
