Clear and structured view on the fundamentals of modeling phase change phenomena in chemical and material engineering Bridging the divide between materials engineering and chemical engineering and providing unique insights in both fields, Guide to Modeling of Phase Change Phenomena in Chemical and Materials Engineering imparts a combination of the heat and mass transfer theory and practical engineering problems referring to phase change phenomena in chemical and materials engineering. The text enables engineers to calculate complex large scale systems, taking into account micro-scale phase change phenomena, and predict complex transport phenomena on the phase change interface including melting, solidification, oxidation, and gasification processes under the influence of convection. To enable a thorough understanding of the models, the book provides selected examples with solutions to work through. Written by a highly qualified academic with significant experience in the field, Guide to Modeling of Phase Change Phenomena in Chemical and Materials Engineering includes information on: Role of modeling in modern engineering, covering goals, advantages, and disadvantages, along with rules of modeling and programming in engineeringMain concepts surrounding modeling of phase change phenomena in engineering, such as mixture models and Euler-Eulerbased modelsPhase change phenomena in materials engineering, covering melting ice in air and water, freezing water in cavities (lakes), and morePhase change phenomena in chemical engineering, covering the drying of solid carbonaceous particles from entrained flows to fixed beds and moreProviding comprehensive coverage of the subject with a plethora of helpful learning aids included throughout the text, Guide to Modeling of Phase Change Phenomena in Chemical and Materials Engineering is an essential resource for students in programs of study related to engineering, chemistry, and chemical engineering, especially Master’s students.

Combining previously unconnected computational methods, this monograph discusses the latest basic schemes and algorithms for the solution of fluid, heat and mass transfer problems coupled with electrodynamics. It presents the necessary mathematical background of computational thermo-fluid dynamics, the numerical implementation and the application to real-world problems. Particular emphasis is placed throughout on the use of electromagnetic fields to control the heat, mass and fluid flows in melts and on phase change phenomena during the solidification of pure materials and binary alloys. However, the book provides much more than formalisms and algorithms; it also stresses the importance of good, feasible and workable models to understand complex systems, and develops these in detail. Bringing computational fluid dynamics, thermodynamics and electrodynamics together, this is a useful source for materials scientists, PhD students, solid state physicists, process engineers and mechanical engineers, as well as lecturers in mechanical engineering.

Bridging the gap between the well-known technological description of gasification and the underlying theoretical understanding, this book covers the latest numerical and semi-empirical models describing interphase phenomena in high-temperature conversion processes. Consequently, it focuses on the description of gas-particle reaction systems by state-of-the-art computational models in an integrated, unified form. Special attention is paid to understanding and modeling the interaction between individual coal particles and a surrounding hot gas, including heterogeneous and homogeneous chemical reactions inside the particle on the particle interface and near the interface between the solid and gas phases.While serving the needs of engineers involved in industrial research, development and design in the field of gasification technologies, this book's in-depth coverage makes it equally ideal for young and established researchers in the fields of thermal sciences and chemical engineering with a focus on heterogeneous and homogeneous reactions.
