Pressure drop in two-phase He I natural circulation loop at low vapor quality
B. Baudouy
Steady state pressure drop in a two-phase He I natural circulation loop has been measured at atmospheric
 pressure. Results are obtained up to 0.2 exit vapor quality for a 14-mm diameter copper tube heated over
 a length of 1.2 m. Pressure drop assessment, done with the momentum balance equation including sub-cooling,
 reveals that the homogeneous model and Friedels friction multiplier associated with Huq and Loths void 
fraction correlations predict data within 15%.
