在气动除霜实验的基础之上 ,运用气体动力学理论、边界层理论 ,对气动除霜的机理进行了探析 ,指出当气流动力作用大于霜层与翅片的粘附功时 ,霜层被吹离翅片表面 .
Based on the experiment of pneumatic defrosting, the mechanism of pneumatic defrosting was analyzed by using gas dynamics theory and boundary layer theory. It is pointed out that when the aerodynamic force is greater than the adhesion work of frost and fin, the frost layer Blow off the surface of the fins.
