以湍流漩涡扩散理论为根据，建立了漩涡与壁面接触时液体温度分布方程．再根据汽泡顶点温度必须高于热力平衡温度的原则，确定了接触周期，该计算分析结果与文献所给出的实验数据吻合较好． Based on the turbulent vortex diffusion theory, the temperature distribution equation of the liquid when the vortex is in contact with the wall is established. According to the principle that the temperature of bubble apex must be higher than the thermal equilibrium temperature, the contact period is determined. The calculation and analysis results are in good agreement with the experimental data given in the literature.
