Experimental Investigation on Steam-Liquid Two Phase Flow Friction in Tubes
Chen Xue-jun, Zhou Fang-de, Chen Li-xun
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.
