Fig. 5From: Pressure drop of two-phase helium along long cryogenic flexible transfer lines to support a superconducting RF operation at its cryogenic test standCalculated results of two-phase frictional multiplier term Φ 2 varying with vapor quality × with our theoretical model are compared with the experimental data, the modified Martinelli–Nelson equation and the homogenous model (Rane et al. 2011) (Courtesy Cryogenics 2011)Back to article page
