液中懸濁粒子の凝集挙動

抄録

Coagulation of particles in the fluid is often observed in nature and it is a multiphase phenomenon utilized in various processes. Coagulation phenomenon is also observed in molten metal system in the same as water and air system. Until now, coagulation of particles such as oxide inclusions, have been focused on because large inclusions raise harmful defects in final products. Therefore, many researches have been performed in the both side of theory and experiment. In this paper, kinetics of coagulation behaviors is summarized for information to analyze the growth rate of aggregates, particle size distribution and so on. In addition, recent researches and issues for coagulation mechanism are introduced briefly in the view point of multiphase phenomenon.
