Abstract
A Wire Mesh Sensor (WMS), based on the measurement of the local
instantaneous conductivity of the two-phase mixture, has been adopted to
characterize the air-water flow in a test section consisting of a horizontal
Plexiglas (transparent) pipe of internal diameter 19.5 mm and total length of
about 6 m. The flow quality ranges from 0 to 0.73 and the superficial velocity
ranges from 0.145 to 31.94 m/s for air and from 0.019 to 2.62 m/s for water; the
pressure ranges from atmospheric pressure to 3.7 bar. The observed flow patterns
are stratified-bubble-slug/plug-annular. The void fraction profiles are derived
from the sensor signals and their evolution in time and space is analyzed and
discussed; the dependence of the signals from the measured fluid dynamic
quantities is discussed too.
Keywords : horizontal two-phase flow, flow pattern, void fraction profiles.
