本文从汽液界面紊流脉动受到抑制的物理基础出发，提出对近界面缓冲层的混合长理论应进行修正，通过试验得到了相应的数学表达式及速度分布，并据此发展了一个新的环状流液膜换热模型。通过与试验值的比较，本文模型的计算结果与现有模型的计算结果相比较更趋于合理。
Based on the physical basis of the suppression of turbulent pulsation at the vapor-liquid interface, this paper proposes that the theory of mixing length of near-interface buffer should be modified, and the corresponding mathematical expressions and velocity distributions obtained through experiments. Based on this, a new Annular flow membrane heat transfer model. Compared with the experimental data, the calculated results of this model tend to be more reasonable than those of the existing models.
