Reducing the Presence of Clusters in Bubble Size Measurements for Gas Dispersion Characterizations

This short communication evaluates a new strategy to sample bubbles in gas dispersion characterizations. Bubble size is measured bidimensional flotation cell using the McGill bubble analyzer under different types of frothers, frother concentrations and superficial rates. The original design this viewer modified, changing deflecting system photograph only fraction entering device. As result, increases ability successfully identify by maximum 20% an automated algorithm. increase caused reduction formation clusters visual field. improvement, which function operating conditions, most significant transition from ellipsoidal/ellipsoidal–turbulent regimes (no or low concentrations) conditions with over-agglomeration field (high rates high concentrations). A comparison parameters obtained proposed systems shows that does not distort estimated distributions. To complement research findings, alternative sampling designs, existing segmentation algorithms, are then improve characterizations at scales.
