Summary

A numerical simulation for calculating the flashing flow characteristics of refrigerants inside short-tube orifices is presented. The refrigerant flow behaviors along short-tube orifices are separated into three sections: subcooled liquid region, metastable liquid region, and two-phase region. Annular two-phase flow pattern is developed from the mass, energy, and momentum equation. The present simulation is corroborated by comparison with the experimental data. The selection charts are also presented to estimate the refrigerant mass flow rate along short-tube orifices in practical applications.
