Résumé

The aim of this thesis is to contribute to a better understanding of the underlying physical phenomena in single-phase and specially flow boiling heat transfer of refrigerants in small channels. For this purpose, well characterized heat transfer experiments have been performed in uniformly heated, single, circular, vertical channels ranging from 0.64 to 1.70 mm in diameter and using R134a, R22 and R245fa as working fluids. Furthermore, flow visualization tests have been carried out to clarify the relation between the two-phase flow behaviour and the boiling heat transfer characteristics.
