摘要: 分析多个活化核心间的热相互作用,利用协同论的基本观点,阐述多核心核化时产生的自组织协同竞争特性。数值模拟了沸腾系统核化中的自组织现象。理论分析结果与文献的试验观察相吻合。在真实的沸腾过程中,活化核心间存在非线性相互作用,自组织的协同理论具有明显的优越经典理论之处。

Abstract: Synergetic concepts have been used to analyze the interactions among active sites or bubbles and the self-organizing effect in nucleation. A dynamic simulation performed to investigate the interactions between the active sites reproduces the self-organizing process. These studies illustrate the experimental observations available in the literature and may provide a more reasonable mechanistic description of nucleation in boiling systems.

Key words: Activation, Boiling, Nucleation site, Self-organization
