Abstract

Waterside flow instability is an undesired phenomenon occurring, under certain circumstances, in sodium heated steam generators used in sodium-cooled fast reactors (SFR). A reliable prediction of two-phase pressure drop is essential to assess the risk of flow instability and establish a stable operating regime in terms of operating parameters. Towards this, experiments have been conducted at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, India, to investigate the two-phase pressure drop over a wide range of water mass flux values. The measured two-phase pressure drop data are compared with the data obtained using available empirical correlations. The relative importance of acceleration, gravity, and frictional components of two-phase pressure drop is studied for vertical upward flow. It is seen that the acceleration component of pressure drop is insignificant, whereas the frictional component is mainly controlling the two-phase pressure drop. Based on the measured data, a correlation has been proposed for predicting the two-phase flow frictional multiplier, closely matching the experimental data.
