Evaluation des méthodes de prévision pour les chutes de pression et le coefficient de transfert de chaleur de condensation à l'intérieur de tubes à rainures internes hélicoïdales.

Evaluation of prediction method for pressure drop and condensation heat transfer coefficient inside internally helically-grooved horizontal tubes.

Auteurs : INOUE N., GOTO M.

Résumé

In this paper, the authors show methods for predicting the pressure drop of two-phase flow and condensation heat transfer coefficients, which were derived from measured friction factor data in single-phase flow experiments of fourteen kinds of internally helically-grooved tubes with 6.35 mm outer diameter. The results were evaluated by comparing the predicted values with experimental data measured by Haraguchi et al. (1994) for an internally helically-grooved tube and by Miyara et al. (2000) for an internally herringbone-grooved tube. The results indicate that the predicted values of pressure drop and condensation heat transfer coefficients agree with the measured data within plus or minus 30% and that the proposed methods can produce accurate predictions for many kinds of internally grooved tubes.
