An Experimental Study on the Flow Characteristics of Oil-Water Two-Phase Flow in Horizontal  Straight Pipes

Abstract

Abstract: The flow patterns and their transitions of oil-water two-phase flow in horizontal pipes
were studied. The experiments were conducted in two kinds of horizontal tubes, made of
plexiglas pipe and stainless steel pipe with 40 mm ID respectively. No. 46 mechanical oil
and tap water were used as working fluids. The superficial velocity ranges of oil and water
were: 0.04-1.2 m.s-1 and 0.04-2.2 m.s-1, respectively. The flow patterns were identified by
visualization and by transient fluctuation signals of differential pressure drop. The flow
patterns were defined according to the relative distribution of oil and water phases in the
pipes. Flow pattern maps were obtained for both pipelines. In addition, semi-theoretical
transition criteria for the flow patterns were proposed, and the proposed transitional
criteria are in reasonable agreement with available data in liquid-liquid systems.
