Abstract

Experimental investigations have been carried out to evaluate the two-phase pressure drop and the holdup for gas-Newtonian liquid flow through helical coils. 24 helical coils and three different liquids were used for the experiments. Empirical correlations have been developed to predict the two-phase friction factor and the liquid holdup as functions of various physical and dynamic variables of the system. Statistical analysis of the correlations suggests that they are of acceptable accuracy.

Abstract

On a mené des études expérimentales afin d'évaluer la perte de charge et la rétention biphasiques pour un écoulement de gaz-liquide newtonien dans des serpentins hélicoïdaux. Vingt-quatre serpentins hélicoïdaux et trois liquides différents ont été utilisés pour ces expériences. Des corrélations empiriques ont été établies pour prédire le facteur de friction biphasique et la rétention de liquide en fonction de diverses variables physiques et dynamiques du système. L'analyse statistique des corrélations suggèrent que leur précision est acceptable.
