Abstract

The development of compact, advanced cooling technology leads to problems involving two-phase flows at micro-scales. We investigate the effect of slip on heated liquid film driven by its own vapor in microchannel. The macroscopic interface shape is found to be sensitive to slip length comparable with the initial film thickness. The slip at the wall tends to elongate the transition film, and can have an effect on the mass flow rate. Calculations reveal that the maximum of the slip velocity is located in the transition region. The present work is a part of the preparation of the SAFIR experiment of the European Space Agency onboard the International Space Station.
