摘要: 本文报道了在高压加热水回路中水平直管内蒸汽-水两相摩擦阻力系数在试验段加热和不加热两种条件下进行的试验研究。检验作者以前所提出、现已作为我国电站锅炉水力计算方法的阻力计算式。结果表明这种计算方法与国外一些计算方法相比,计算精度高,方法简便。

Abstract: This paper described the experimental results of frictional pressure drop of steam-water two-phase flow in a high pressure water leap. The experiments were conducted under the hinted and unheated conditions. The purpose of the experiments is to check the equation of frictional pressure drop that has been as the standard hydraulic equation of frictional pressure drop in power boiler. The results showed that the equation is more convent ant and accurate to use in comparison with other frictional pressure drop equations.

Key words: 两相流动, 摩擦阻力
