FLOWING CONDENSATION HEAT TRANSFER LAW OF STEAM IN COMPLEX CHANNELS

作者对水蒸汽在三种结构的网状波纹形变截面流道中的流动凝结问题进行了研究。文中具体阐述了凝结换热理论模型的建立、流道结构、实验研究的系统和工况，提出了表微饱和水蒸汽在该类复杂结构流道中流动时所服从的凝结换热规律，分析了质量流率、蒸汽压力、液膜、流动方向等因素对流动凝结换热的影响。

The authors studied on flowing condensation of steam in grid type of corrugated channel with three kinds.of configuration. The paper describes the foundation of theoretical model for flowing condensation heat transfer, channel geometry, experimental tests and results. The flowing condensation heat transfer law of steam in complex corrugated channels is obtained.The factors, such as mass flow rate, steam pressure, liquid film and flowing direction affecting on condensation heat transfer are discussed.
