Experimental analysis on metastable flow of R410A through capillary tubes.

Author(s) : FIORELLI F. A. S., SIMÕES SILVA C. A.

Summary

This work presents the results of an experimental study on the occurrence of the delay of vaporization in the flow of refrigerant blends in adiabatic capillary tubes. Experiments were carried out for R410A using the capillary tubes laboratorial unit of the Mechanical Engineering Department of the University of São Paulo. Sensors were properly positioned along the capillary tubes, concentrated in the region where the delay of vaporization is expected to happen, to allow an accurate determination of the flashing point inception for a several operational conditions and geometries. A total of 44 experimental points, collected from 27 runs, allowed the characterization of the effect of some geometric and operational parameters on the underpressure of vaporization and metastable region length.
