Abstract

Vertical three phase air‐water‐oil 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 qualititive terms depending on the nature of the flow pattern present. Generally for the water dominated regime below f~0~ = 0.5 the overlying oil annular film protected the water annular from the momentum effects of the gas. Above f~0~ = 0.5 the opposite took place and the water annulus film thinned until inversion to oil dominated flow occurred. This was a region of intense mixing of the liquid phases and the hold‐up rose dramatically.
