ABSTRAKT

Transient two-phase flow experiments are carried out in a horizontal pipe (4.09 m long and 206 mm ID) to investigate the variation of temperature and void fraction during the process of blowdown. Large pressure gradient is seen in the cross-section with higher temperatures at the bottom: the vapour at the top is saturated while the liquid at the bottom is superheated. Also, there is an evidence of a vapour annulus existing throughout the blowdown.
