Abstract
This work investigates the use of an optical tomography system as a non-intrusive measurement tool for the study of horizontal multiphase flow. Dispersed bubble flow of water and air is captured with a set of three high-speed video cameras.
Bubble position data is reconstructed from the cameras's images to analyze its structure inside the pipe. Three pipe diameters are used and a set of different Reynolds numbers are chosen at two investigation points along the pipe.
Commonly, multiphase flows are studied using a top-view imaging technique. Thus, in order to assess the capability of the tomographic system to measure flow properties, a comparison between top-view imaging and tomography is performed. The 3D tomography data is also used to characterize the flow of bubbles. A statistical analysis of the sizes, velocities, positions and shapes is presented.
