Transfert de chaleur lors de l'ébullition de CO2 à l'intérieur de tubes horizontaux. 1. Régime d'écoulement et prévision de l'assèchement.

CO2 flow boiling heat transfer in horizontal tubes. 1. Flow regime and prediction of dryout.

Auteurs : SUN Z., GROLL E. A.

Résumé

The possible flow patterns of CO2 flow boiling in horizontal tubes were studied based on analyses found in the literature. Annular flow is found to be the predominant flow pattern for normal operating conditions. The mechanisms required to sustain annular flow were examined; the occurrence of dryout is an important phenomenon in annular CO2 flow. A model to predict the onset of dryout and the location of complete dryout for CO2 flow boiling in horizontal tubes is described and evaluated.
