Abstract

The basic evaporating two-phase flow mechanism in micro- channels is introduced. This flow is accompanied by a very high heat transfer coefficient and can remove very high heat fluxes at low temperatures, thus, making it attractive for micro device cooling applications. An experimental micro- channels chip was fabricate by means of a photolithography process, in order to study the flow mechanism involved in such flow. The results show that there is periodic behavior in evaporating two-phase flow in micro-channels, with a few harmonics.
