Multiphase flows are very popular in ironmaking and steelmaking processes and are characterized as follows:(1) The temperature of fluids in metallurgical reactors is higher than about 1500°C, hence measurements of transport phenomena (fluid motion, heat and mass transfer) are very difficult.(2) The flow in the reactors is highly turbulent (turbulence components are usually larger than mean flow values) and chemical reactions take place at the same time. Many “cold model” experiments have been carried out due to the difficulty in doing measurements under realistic conditions. Water, oil (silicone oil, pentane, liquid paraffin, etc.) and metals with low melting temperatures (mercury, Wood's metal, etc.) are Used as working fluids. Transport phenomena encountered in ironmaking and steelmaking processes (hot metal pretreatment, converter, second refining processes, etc.) are covered here and previous experimental and theoretical results on this subject are reviewed
