摘要
Boiling phenomena are with highly complex nonlinear and nonequilibrium characteristics, which cause diversity and complexity of boiling nucleation. In the present paper, an experimental investigation was conducted to investigate the nucleate boiling behavior on a very fine heating wire. Using zoom routine and CCD camera system, the dynamical process of nucleate boiling was visually observed and several modes of jet flows were explored during nucleate boiling. This phenomenon is quite different from the usual observation of nucleate boiling. High-energy liquid jet, fog-like jet, cluster-like jet, bubble-forming jet, bubble-bunch jet and bubble-top jet were described in detail. The microscopic mechanism concerning the phenomena was discussed. (C) 2002 Published by Elsevier Science Ltd.
