| 摘 要： | 对自然对流条件下施加20 kHz频率的超声波和未施加超声波两种作用机制下平板表面的结霜现象进行了微观可视化研究，对比分析了有无超声波作用下不同冷表面温度对霜层厚度的影响。研究显示，冷表面霜层在施加超声波作用后仅有少量生长，霜层分布相对规则，由一簇簇“霜线”组成。结果表明，超声波对平板表面霜层的生长具有显著的抑制作用。

| Abstract: | The effect of ultrasound on restraining the occurrence of frost on the flat surface was studied.The frost phenomena on the flat surface with and without 20 kHz ultrasound under natural convection conditions were visually studied.The effects of different cold surface temperatures on the frost thickness with and without ultrasound were compared and analyzed.The experimental results indicated that the frost layer grew very slowly with the effect of ultrasound,and the frost layer composed by "frost line" was mo... |
