Modeling Multiphase Materials Processes: Gas-Liquid Systems describes the methodology and application of physical and mathematical modeling to multi-phase flow phenomena in materials processing. The book focuses on systems involving gas-liquid interaction, the most prevalent in current metallurgical processes. The performance characteristics of these processes are largely dependent on transport phenomena. This volume covers the inherent characteristics that complicate the modeling of transport phenomena in such systems, including complex multiphase structure, intense turbulence, opacity of fluid, high temperature, coupled heat and mass transfer, chemical reactions in some cases, and poor wettability of the reactor walls. Also discussed are: -Solutions based on experimental and numerical modeling of bubbling jet systems -Recent advances in the modeling of nanoscale multi-phase phenomena -Multiphase flows in micro-scale and nano-scale channels and reactors Modeling Multiphase Materials Processes: Gas-Liquid Systems will prove a valuable reference for researchers and engineers working in mathematical modeling and materials processing.

Preface
Multiphase flow phenomena abound in many materials processing operations, including gas-stirred ladles, blast furnaces, and the like. This book focuses primarily on systems in which liquid and gaseous phases coexist. In general, such systems are complex and difficult to characterize. The phases can be continuous or dispersed, with mass, momentum, and energy exchange across the interfaces. For the past few years, there has been a heavy focus on relating the interfacial fluxes to measurable macroscopic properties of the flow so as to provide a fundamental understanding of the mixing process. Significant advances have also been made in the application of computational and experimental techniques to multiphase transport phenomena in materials processing operations. This book presents the application of these modeling tools to dispersed gas–li
