Dynamic characteristics of microscale boiling

Microscale boiling displays some quite unusual characteristics, like the oc currence of the so-called "fictitious boiling". This paper conducted the th ermodynamic and dynamic analyses regarding the phase change and bubble nucl eation in microchannels. The role of perturbations on the dynamics of bubbl e embryos was investigated, whence the possible causes corresponding to the depression of bubble nucleation in microscale boiling were proposed throug h stochastic analysis. The external perturbations produced by pressure impu lses accompanied with embryo growth and collapse could markedly alter the d ynamic characteristics of bubble growth.
