Two-phase cryogenic flow measurement

The measurement of mass flow rate of the two-phase cryogenic flow is attracting a lot of interest lately due to the possible special applications for the fluids it measures. The combination solid/liquid hydrogen or slush hydrogen, solid/liquid nitrogen or slush nitrogen are only few of the two phase cryogenic flow that can be of interest for various applications because of the greater cooling performance, greater compactness and lighter weight. The applications of such fluids include but are not limited to cooling of superconducting cable, fuel for space shuttles, large cryogenic installations and superconducting accelerators. In this paper we report on the two-phase cryogenic flow measurement based on the density capacitive.
