摘要
通过系统介绍水平管内凝结的气液两相流型,以及不同坐标形式的流型图,得出水平管内环状流、波状流和雾状流之间转换的判据。另外,列举了水平光滑管和内螺纹管内凝结换热的经验型关联式,为计算管内凝结换热提供依据。并提出了下一步研究工作的建议。
Through introducing flow patterns and maps with different coordinates by the numbers,transition criteria between annular flow,wave flow and mist flow inside horizontal tubes is obtained.In addition,experiment correlations about condensation heat transfer inside horizontal plain and micro fin tubes are listed.And put forward the next study suggestion.
