摘要:
本文研究了表面特性对超声波脱除冷表面冻结液滴的影响，对不同表面特性下超声波对不同粒径和不同冻结时间冻结液滴的脱除效果进行了对比分析. 试验结果表明，超声波可瞬间脱除冷表面冻结液滴，且随着表面接触角的增加，冷表面冻结液滴的脱除概率逐渐增大；冻结液滴粒径越大，冻结时间越长，表面特性对超声波脱除冻结液滴的效果越显著；与普通铝表面上冻结液滴脱除状况相比，表面接触角136°时，超声波可完全脱除其表面上冻结液滴. 试验结果为疏水表面应用于超声波抑/除霜提供了数据支撑.
Abstract:
Effects of surface characteristics on frozen water droplets removal from cold surfaces by ultrasound are experimentally studied and comparative analysis of effects of ultrasound are carried out on the removing of frozen water droplets with different size and freezing time from cold surface with different surface characteristics. The experimental results indicate that the frozen water droplets on cold surfaces can be instantaneously removed by ultrasound and the removal probabilities of frozen droplets gradually increase with the increase of surface contact angle. It is also found that the surface characteristics can significantly affect the removal of frozen water droplets in bigger size and longer freezing time. In addition，compared with the ordinary aluminum surface，the frozen water droplets on cold surface with surface contact angle of 136° can be completely removed by means of ultrasound. The experimental results provide a data support for hydrophobic surface applied in the ultrasonic anti-frost/defrosting.
