| 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 Friedel’s friction multiplier associated with Huq and Loth’s void fraction correlations predict data within 15%. |
