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 from our present data.It can be applied 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.]
