| 摘 要： | 根据成核密度的理论关系式，模拟了不同温差条件下冷凝表面的液滴生长过程，结果显示：液滴尺寸分布具有分形特征，分形维数随着温差的增大而增大；冷凝表面的热交换系数随着温差的增大也相应增大，模拟结果与实验结果相符。

| Abstract: | In this paper,based on a theoretical expression of droplet nucleation density,droplet growth processes on condensing substrate is simulated under different temperature differences.According to the simulation results,it is concluded that：droplet size distribution is fractal,the fractal dimension increases with the temperature difference, and heat transfer coefficient also increases with the temperature difference,which is in good accord with experimen-tal results. |
