A cold model experiment on the hetero-coagulation of inclusion particles in liquid steel has been performed to verify the hetero-coagulation model developed in the previous study. In this study, a cold model experiment of coagulation in electrolyte solution has been conducted in an agitated vessel under turbulent flow condition. Binary suspension of polymethyl methacrylate having different sizes was used in the experiment. Thus, this experiment means a pseudo hetero-coagulation phenomenon. The experimental results have been compared to the calculation ones. As a result, the model has almost agreed with experimental values on a change in particle number density with time. In addition, a generation behavior and a structure of aggregates have been discussed based on the calculation results.
