摘要
从试验和理论上研究了螺旋管内气液两相流动特性，得出了平均截面含气率与容积含气率图，并采用不同模型，对螺旋管内主要流型平均截面含气率和摩阻压降进行了推导和计算，计算结果与试验数据符合较好。
お? Experimental and theoretical studies are carried out about the characteristics of the air-water two-phase flow.The correlative graphs for average section void fraction and volumetric void fraction are obtained.By using several different models,formulas for the average section void fraction and friction resistance pressure drop of main flow patterns in helical-coiled tubes are derived and calculations have been made.The calculation results agree well with experimental results.
