Un passage en revue des caractéristiques du transfert de chaleur du dioxyde de carbone lors de l'ébullition en écoulement.

A review on carbon dioxide heat transfer characteristics during flow boiling.

Auteurs : DUCOULOMBIER M., COLASSON S., HABERSCHILL P.

Résumé

An original review on carbon dioxide (CO2) flow boiling characteristics is proposed through a wide range of diameters and temperatures representing promising applications such as mobile air-conditioning, heat pump water heater and cascade commercial refrigeration. Although there is a consensus that CO2 outperforms conventional refrigerants due to its nucleate boiling dominated heat transfer, it is still not clear which phenomenon induces the decrease of the heat transfer coefficient at moderate to high vapour quality. Based on the open literature, a heat transfer database was built from flow boiling experiments in circular tubes including 216 test conditions. Cross-references among the data and comparisons at varying diameters allow to better discriminate the contribution of nucleate boiling suppression, partial dryout and distribution problems.
