Experimental verification of the four-sensor probe model for flow diagnosis in air water flow in vertical pipe

Measuring the volumetric flow rate of each of the flowing components is required to
be monitored in production logging applications. Hence it is necessary to measure the flow
rates of gas, oil and water in vertical and inclined oil wells. An increasing level of interest has
been shown by the researchers in developing system for the flow rate measurement in
multiphase flows. This paper describes the experimental methodology using a miniature, local
four-sensor probe for the measurement of dispersed flow parameters in bubbly two-phase flow
for spherical bubbles. To establish interdependent among different parameters corresponding to
dispersed flow, the available model has been used to experimentally obtain different
parameters such as volume fraction, velocity and bubble shape of the dispersed phase in the
bubbly air-water flow.
