New insights into the behaviour of the metastable region of an operating capillary tube.

Type of article: Article

Summary

The study examines the mass flow rate of R22 in an adiabatic capillary tube. The metastable region of an operating capillary tube was found to be much more predictable than previously reported in the literature. A new data acquisition technique revealed a hysteresis effect in the mass flow rate as the level of inlet subcooling is increased and decreased. The result is explained. It is predicted that this finding will have an impact on the future of capillary tube data acquisition, and the fundamental understanding of capillary tube flow.
