Cette étude a eu pour objectif de préciser certains phénomènes caractéristiques des écoulements diphasiques rencontrés lors du transport par oléoducs des bruts pétroliers à teneur en gaz faible ou moyenne. Des expériences ont été réalisées à basse pression sur une boucle diphasique eau-air de diamètre 0,045 m et de longueur 50 m. Les mesures de présence de phase locale et de pression effectuées à la paroi pour des vitesses débitantes du liquide et du gaz variant respectivement entre 0,5 et 2 m/s et 0,3 et 10 m/s, ont permis d'accéder aux principales grandeurs cinématiques des écoulements à poches. A l'aide des méthodes classiques de l'analyse statistique, on a caractérisé l'aspect aléatoire de ces écoulements, la longueur d'établissement de...
