A STUDY ON METASTABLE FLOW ON REFRIGERANT THROUGH CAPILLARY TUBES
Abstract
The metastable flow phenomenon of Refrigerant −12 through capillary was experimentally and analytically investigated. A correlation for the determination of underpressure of vaporization was presented. A numerical model for steady-state two-phase flow in capillalry tubes was developed. The effects of the thermodynamic non-equilibrium during vaporization and the relative velocity between vapor and liquid on the total pressure drop in the capillary tube, on the mass flux, and on the capillary tube length, were analyzed.
