Particle Technology and Engineering presents the basic knowledge and fundamental concepts that are needed by engineers dealing with particles and powders. The book provides a comprehensive reference and introduction to the topic, ranging from single particle characterization to bulk powder properties, from particle-particle interaction to particle-fluid interaction, from fundamental mechanics to advanced computational mechanics for particle and powder systems.

The content focuses on fundamental concepts, mechanistic analysis and computational approaches. The first six chapters present basic information on properties of single particles and powder systems and their characterisation (covering the fundamental characteristics of bulk solids (powders) and building an understanding of density, surface area, porosity, and flow), as well as particle-fluid interactions, gas-solid and liquid-solid systems, with applications in fluidization and pneumatic conveying. The last four chapters have an emphasis on the mechanics of particle and powder systems, including the mechanical behaviour of powder systems during storage and flow, contact mechanics of particles, discrete element methods for modelling particle systems,and finite element methods for analysing powder systems.

This thorough guide is beneficial to undergraduates in chemical and other types of engineering, to chemical and process engineers in industry, and early stage researchers. It also provides a reference to experienced researchers on mathematical and mechanistic analysis of particulate systems, and on advanced computational methods.

Provides a simple introduction to core topics in particle technology: characterisation of particles and powders: interaction between particles, gases and liquids; and some useful examples of gas-solid and liquid-solid systemsIntroduces the principles and applications of two useful computational approaches: discrete element modelling and finite element modellingEnables engineers to build their knowledge and skills and to enhance their mechanistic understanding of particulate systems

Particle Technology and Engineering: Fundamentals and Computational Methods, Second Edition provides a comprehensive reference and introduction to the topic, ranging from single particle characterization to bulk powder properties, from particle-particle interaction to particle-fluid interaction, from fundamental mechanics to advanced computational mechanics for particle and powder systems. The book begins with a theoretical framework, with the first eight chapters focusing on properties of single particles and powder systems, their characterization, particle-fluid interactions, and the mechanics of particle and powder systems. These foundational chapters provide examples and exercises to aid in understanding these concepts. The last three chapters build upon this overview to provide more advanced practical guidance focus on modeling and simulations for particle systems and powder processing, including discrete element methods, finite element methods, and machine learning - case studies and complete algorithm models are included to demonstrate the modeling procedures and capabilities. This book serves as an invaluable comprehensive guide to students at postgraduate and late undergraduate level within chemical engineering, as well as other engineering disciplines involving particle technology and chemical processes. This book will also be incredibly useful to early-stage researchers working in chemical process engineering and experienced researchers on mathematical and mechanistic analysis of particulate systems, and on advanced computational methods. This book would also be a useful reference for students, industrial researchers and process designers working in other industries, such as pharmacy, mechanical and civil engineering, food processing and fast-moving consumer goods.Provides a simple introduction to core topics in particle technology: characterisation of particles and powders: interaction between particles, gases and liquids; and some useful examples of gas-solid and liquid-solid systemsIntroduces the principles and applications of two useful computational approaches: discrete element modelling and finite element modellingEnables engineers to build their knowledge and skills and to enhance their mechanistic understanding of particulate systems

Discrete Element Methods (DEM) is a numerical technique for analysing the mechanics and physics of particulate systems. Originated in the late seventies for analysing geotechnical problems, it has seen significant development and is now employed extensively across disciplines. Produced in celebration of the 70th Birthday of Colin Thornton, this book contains a selection of papers concerning advances in discrete element modelling which were presented at the International Symposium on Discrete Element Modelling of Particulate Media held at Birmingham, UK on 28-30th March, 2012. The book showcases the wide application of discrete element modelling in gas-solid fluidisation, particulate flows, liquid-solid systems and quasi-static behaviour. It also reports the recent advancement in coupled DEM with computational fluid dynamics, Lattice Boltzmann Methods for multiphase systems and the novel application of DEM in contact electrification and fracture of granular systems. Aimed at research communities dealing with this technique in the powder handling and formulation industries, this will be a welcomed addition to the literature in this area.
