立体式螺旋管内空气-水两相流摩擦阻力压力降实验研究

摘要

文章以空气-水为工质,对立式螺旋管内空气-水两相流摩擦阻力压力降进行了实验研究.在对实验结果进行分析时,以前人的有关研究为基础,提出了一种新的两相流动压力降计算公式,适用于压力不大于1 Mpa,质量流量不大于150 kg/(m2·s)的低压低质量流量场合.%Frictional pressure drop of air-water two-phase flow was studied in a vertical helicoidal coiled tube. Based on previous studies, a new calculation formula was obtained flora our present data. It can be apphed in the situation of low pressure ( lower than 1 MPa) and low mass flow [ lower than 150 kg/(m2 · s) ]. [ Ch,5 fig. 8 ref. ]
