Abstrakt
Miccroscale boiling displays some quite unusual characteristics, like the occurrence of the so-called "fictitious boiling". This paper conducted some arguments on the thermodynamic and dynamic characteristics of the phase change and bubble nucleation in microchannels or microstructures. The cluster model was proposed to describe the density fluctuation in superheated liquid, and furthermore, the kinematics of a cluster was analyzed using Brownian motion. The analyses explore that the scale of microstructures has significant importance on the kinematics of a cluster and the boiling nucleation.
