本文研究了大气压下不锈钢和过冷氟里昂113液膜系统的湿锋速度和表面热流密度分布。对于高过冷度和流量，湿锋速度随着入口过冷度和流量的乘积而增加。一个二维的分析用于推导表面热通量。结果表明，由于过冷气膜前锋的不规则性，导致了淬火前锋前表面的热流密度随液体过冷度的增加而增加。
The wet front velocity and the surface heat flux distribution are investigated with a system of hot stainless steel and a subcooled Freon 113 liquid film at atmospheric pressure. For high subcoolings and flow rates, the wet front velocity increases with the product of the inlet subcooling and flow rate. A two-dimensional analysis is used for deriving the surface heat flux. The result shows that, arising from the fact that the subcooled film front is irregular, the heat flux at the surface ahead of the quench front increases with increasing liquid subcooling.
