However, two-phase flow is an extremely complicated physical phenomenon
occurring particularly in the petroleum industry during the production
and the transportation of oil and gas due to its unsteady nature and
high attendant pressure drop. This may eventually damage the pipe
system, therefore the complexity of the potential flow regimes present
within these pipelines has attracted considerable research interest to
improve our understanding of two-phase flow phase distribution in a pipe
system under various processing conditions. The spatial distribution of
the phases inside the pipe and the pipe geometry play an extremely
important role in the accurate determination of pressure gradient and
flow hydrodynamic characteristics. The flow patterns and the void
fraction are one of the key parameters in two phase flow. The two phase
flow in vertical pipes is symmetrical about the pipe axis and is
governed by the interaction between the liquid inertia, buoyancy,
gravity and surface tension forces. However flow patterns and the void
fraction in horizontal pipes is governed by the density segregation
(Bhagwat and Ghajar, 2012).
A vital characteristic of two-phase flow
is the presence of moving interfaces and the turbulent nature of the
flow that make theoretical predictions of flow parameters greatly more
difficult than in single-phase flow. Thus, experimental measurements
play an important role in providing information for design, and
supporting analysis of system behavior. Because of this, there is a real
need to make certain measurements of void fraction distribution for
model development and testing.

ABSRACT - [ Total Page(s): 1 ]The scope of this work was to make detailed analysis of phase distribution in a horizontal pipe. This detailed analysis has been successfully carried out. Data obtained from wire mesh sensor (WMS) were used for the analyses. The operating fluid considered was an air/silicone oil mixture within a 6 m horizontal pipe with internal diameter of 0.067 m. The gas superficial velocities considered spans from 0.047 to 4.727 m/s, whilst liquid superficial velocities ranged from 0.047 to 0.4727 m/s. The w ... Continue reading---
