摘　　要： 本文在高压条件下对水平布置的内螺纹管汽水两相流摩擦压降特性进行了比较系统的试验研究。两根内螺纹管的实测平均内径分别为11.69mm和35.42mm,试验压力9.81～20.59MPa,质量流速345～3560kg/m^2·s.蒸汽干度从0到1.0。试验在西安交通大学高压电加热水回路上进行。对试验结果进行了分析,给出计算内螺纹管摩擦压降的关联式。 The paper presents experimental results on frictional pressure drop of high pressure steam-water two phase flow in two horizontal ribbed tubes with mean inside diameter of 16.69mm and 35.42mm at test pressure ranging from 9.81 to 20.59 MPa, mass velocity from 345 to 3560 kg/m2 s and steam quality from 0 to 1. The tests were performed in the high pressure electric heated hydraulic test loop of Xian Jiao I'ong University. Based on test results, a calculation formula for the frictional pressure drop of ribbed tubes is proposed.
