Pradhan, Suman and Mishra, Rakesh (2015) Measurement of properties of a dispersed phase in air-water multiphase flow using novel four-sensor probe and orthogonal high speed cameras. In: FLUVISU 2015, 16th-20th November, Pleumeur-Bodou/Lannion, France. (Unpublished)

Measurement of the volumetric flow rate of each of the flowing components in multiphase flow is required to be monitored in production logging applications. Thus, an increasing level of interest has been shown by researchers worldwide in making flow rate measurements in multiphase flow accurate to a high level. A new generation of tomographic instruments, which enable the measurement of the instantaneous local velocity vector and the instantaneous local volume fraction of the dispersed phase, are now being introduced. However validation and calibration of such instruments is very important to enable quality assured measurements.

This paper introduces a camera based calibration system for local 4-sensor probes which can be used to quantify the bubble-probe interaction and the accuracy with which the probe can measure velocity vector, for air bubbles in water and oil droplets in water
