Droplets size evolution of dispersion in a stirred tank

Popis výsledku v původním jazyce

Dispersion of two immiscible liquids is commonly used in chemical industry as well as in metallurgical industry e.g. extraction process. The governing property is droplet size distribution. The droplet sizes are given by the physical prperties of both liquids and flow properties inside a stirred tank. The first investigation stage is focused on in-situ droplet size measurement using image analysis and optimizing of the evaluation method to achieve maximal result reproducibility. The obtained experimental results are compared with multi phase flow simulation base on Euler-Euler approach combined with PBM (Population Balance Modelling). The population balance model was, in that specific case, simplified with assumption of pure breakage of droplets.
