Abstract
This work presents the analysis of phase fraction distribution in bubble column reactor using KT-1 signature and fractal dimension. The experiment was carried out using X-ray CT scanner at Leibniz University Hannover. Convolution back projection algorithm is used to obtain the cross-sectional attenuation coefficient distribution. Individual phase distributions of the three phases (air, water and PVC), across the column cross-section, have been obtained using dual energy X-ray tomography. This paper reports measurement of phase fraction distribution at a cross-section level located at 3.2m from the inlet. The effect of variation of PVC concentration on phase fraction distribution of air and PVC has been investigated. Analysis of reconstructed phase fraction using KT-1 signature and fractal dimension reveals interesting information regarding the flow regime transition and mixing phenomenon in the bubble column.
