提出了沸腾的最小模型。随着底板温度的升高，模型显示出三个连续的阶段；传导沸腾、成核沸腾和薄膜沸腾。在成核状态下，热通量随着底板温度的升高而增加，而在薄膜沸腾状态下则降低。在沸腾阶段，最大李亚普诺夫指数为正，这意味着沸腾现象是时空混沌的。
A minimal model for boiling is proposed. With increasing temperature of a bottom plate, the model shows three successive phases; conduction, nucleate, and film boiling. In the nucleate regime the heat flux increases with the temperature of the bottom plate, while it decreases in the film boiling regime. In the boiling phase, the maximum Lyapunov exponent is positive, implying that the boiling phenomena are spatiotemporally chaotic.
