摘要
摩擦阻力计算是管内两相流动中的一个基本问题。本文在高压加热水回路中对水平直管内蒸汽-水两相摩擦阻力系数进行了试验研究。试验是在试验段加热和不加热两种条件下进行的,对本文作者之一提出的现己作为我国电站锅炉水力计算方法的摩擦阻力计算式进行了试验研究和论证。试验结果证明这种计算方法精度高,计算方法简便,优于现有的国外计算方法。
Flow friction calculation is one of the basic problems of two phase flow in tubes. Tests were conducted on steam-water two phase flow in horizonal straight tubes for HP feed water circuits with or without simultaneous heating in the testing section. Verification tests of flow friction calculation show that the methods of its calculation as suggested by one of the authors & adopted in domestic boiler design is highly satisfactory, easy to handle, and superior to methods used abroad.
