【摘要】 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．更多还原

【Abstract】 Based on the theroy of turbulent vortex diffusion, an equation of temperature distribution of fluid during the contact of vortex with the wall is established. Based on the principle by which the top temperature of the bubbles has to be higher than the temperature of thermodynamic equilibrium, the contact period is determined. The results of computing and analysis coincide with experimental data gi en by literatures.更多还原
