Abstract
Microscale boiling displays some quite unusual characteristics, like the occurrence of the so-called "fictitious boiling". This paper conducted the thermodynamic and dynamic analyses regarding the phase change and bubble nucleation in microchannels. The role of perturbations on the dynamics of bubble embryos was investigated, whence the possible causes corresponding to the depression of bubble nucleation in microscale boiling were proposed through stochastic analysis. The external perturbations produced by pressure impulses accompanied with embryo growth and collapse could markedly alter the dynamic characteristics of bubble growth.
