Abstract

Three methods for predicting the in situ liquid volume fraction for the upward flow of gas-liquid mixtures in inclined pipes have been tested against available data from the literature. Combined with the results of an earlier paper, a total of seven methods have been compared. It is demonstrated that for angles of up to 10°, pipeline inclination has little effect on the predicted holdup. Correlations arc recommended for use under specified conditions. On a compare, avec les resultats deja publics, ceux de trois methodes servant a prevoir la fraction du volume de liquide retenu (in situ) lors de l'ecoulement ascendant des melanges de gaz et de liquides dans des tuyaux inclines. Si l'on combine les resultats de la presente etude avec ceux d'un travail precedent, la comparaison embrasse sept methodes. On demontre que, pour des angles allant jusqu'a 10°, l'inclinaison des pipe-lines n'a que pen d'effet sur la retenue prevue. On recommande l'emploi de correlations dans des conditions specifiees.
