## Abstract Vertical three phase airβwaterβoil data in a. 0.026 m i.d. pipe were presented. The liquid holdup data presented as a complex pattern against f~0~ the oil liquid volumetric ratio for annular flow at one value of total superficial liquid velocity. The form of the pattern was explained in
Gas-liquid interfacial profiles in plug flow for both upward and downward flows were obtained using semi-supermultiple point-electrode probes, comprising 67 sensing tips arranged on a tube diameter. Typical interfacial profiles are demonstrated for both flows. Close inspection of the profiles reveal
## Abstract Gas holdup has been measured in an 83βmm diameter, 2.2βm high column at high gas superficial velocities β 0.22 to 2.7 m/s β and at liquid (water) superficial velocities of 0 to 0.47 m/s, by means of a differential pressure transducer. The equation of Hills (1976) based on the slip veloc
