Summary

R134a single-phase and two-phase flow heat transfer in a stainless steel cylindrical tube of 1.68 mm of internal diameter were investigated. The results are presented in the form of boiling curves. Review of literature and the results of own experiments showed differences between curves made for conventional channels and minichannels. The boiling curves evidenced the existence of boiling hysteresis and the phenomenon of zero boiling crisis. Significant influence of flashing process on minichannels flow boiling curves was presented.
