Abstract

The metallurgical process involves complex phenomena comprising high temperature, the multiphase flow, and the physical and chemical reactions in the process reactors. Because of the complexity of the metallurgical process and the limitation conditions for the direct measuring and observation, numerical and physical simulations have become indispensable and effective tools to analyze and reproduce the transport phenomena and mechanisms occurring in the process. Transport phenomena of the gas-liquid two-phase flow plays a dominant role in process metallurgy since their respective movement laws govern the kinetics of the various physical phenomena in the metallurgical reactors. The gas-liquid two-phase flow has complex interface structures, and the accuracy of the interfacial momentum transfer models, including the interfacial forces, which is one of the keys to predicting the distribution of gas phase in the two-phase flow system successfully. This paper is aiming at reviewing the two-phase flow models based on the Euler-Euler system, the interfacial force model, and the turbulence model for gas-liquid two-phase flow. The use and extent of numerical and physical simulation for transport phenomena of two-phase flow in the steelmaking and casting processes are summarized and explored, including the basic oxygen furnace, electric arc furnace, refining, tundish, and molds. The methods and typical application in the numerical and physical simulation of gas-liquid two-phase flow will provide useful guides for the research.

Key words: metallurgical process gas-liquid two-phase flow numerical simulation physical simulation
