Recognition of two-phase flow patterns with the use of dynamic image analysis

Abstract This research work aimed at developing techniques for the recognition of two-phase flow patterns using image analysis. Flow was realized in a flat rectangular channel. Information recorded with a CCD camera, was analysed using the authors' own software. The change in the grey level value from the recorded flow realizations was investigated. The results of this analysis allowed identification of the two-phase flow structures obtained. Stochastic analysis of the fluidization process was also carried out.
