在前人实验的基础上，对知塞顶面上油膜的流动形式、热力学状态、传热方式和 蒸发形态进行了详细的理论分析，否定了汽垫存在的可能性，进而建立了一种以突出 油膜动态行为为特点的油膜雾化工作过程的半经验数学模型。定量地分析了各种传热 方式在油膜蒸发和燃烧中的作用。计算值与实测值比较吻合。 Based on the previous experiments, a detailed theoretical analysis of the flow pattern, thermodynamic state, heat transfer pattern and vaporization pattern of the oil film on the top surface of the stopper has been given, which negates the possibility of the presence of the vapor cushion. Then, Semi - empirical Mathematical Model of Oil Film Atomizing Process with Stressing Dynamic Behavior of Oil Film. Quantitative analysis of the various modes of heat transfer in the film evaporation and combustion role. The calculated value is in good agreement with the measured value.
