It describes various drag models, turbulence models, and kinetics models required for CFD simulations of CLC and covers single reactor, partial, and full-simulations, single/multi-stage as well as single-particle simulations, and CLC with reverse flow.

The book describes the clean coal technology of chemical looping combustion (CLC) for power generation with pure CO2 capture. The focus of the book is on the modeling and simulation of CLC. It includes fundamental concepts behind CLC and considers all categories of fluidized beds and reactors, including a variety of oxygen carriers. The book includes process simulations with Aspen Plus® software using coal, natural gas, and biomass and computational fluid dynamics (CFD) simulations using both the Eulerian and Lagrangian methods. It describes various drag models, turbulence models, and kinetics models required for CFD simulations of CLC and covers single reactor, partial, and full-simulations, single/multi-stage as well as single-particle simulations, and CLC with reverse flow. A large number of examples for both process simulations using Aspen Plus and CFD simulations using a variety of fluidized beds/reactors employing both the two-fluid and Computational Fluid Dynamics / Discrete Element Method (CFD-DEM) model are provided. Modeling and Simulation of Fluidized Bed Reactors for Chemical Looping Combustion will be an invaluable reference for industry practitioners and researchers in academic and industrial R&D currently working on clean energy technologies and power generation with carbon capture.

This book presents the advanced theory and application of the combined Computational Fluid Dynamics – Discrete Element Method (CFD-DEM) to multiphase flow simulations of the gas and bio-particulate matter of non-uniformly shaped biomass.

This book presents the advanced theory and application of the combined Computational Fluid Dynamics – Discrete Element Method (CFD-DEM) to multiphase flow simulations of the gas and bio-particulate matter of non-uniformly shaped biomass. It explores how DEM can simulate the complex behaviour of biomass particles, such as their packing in the multiphase flows that occurs in the agricultural product processing industries. It offers an overview of aerodynamic systems, such as cyclone separators, used in the agricultural processing industry. A detailed description of DEM modeling, including the particle-particle, particle-boundary, and particle-fluid interactions in the context of biomass particles of varying sizes and shapes, is provided. Coverage includes the critical application of CFD-DEM simulation technology in designing and optimizing grain handling and processing equipment and the application of extended DEM to other granular flows of complex particles like sand, powders, and dust from mines where clumping and agglomeration occur. The application of DEM in modeling and simulation of complex multiphase systems can help improve productivity, reduce costs, and increase efficiency in the agricultural industry.

This book includes state-of-the-art papers in manufacturing engineering and processes, including computer-aided design and manufacturing, environmentally sustainable manufacturing processes, modeling, analysis, and simulation of manufacturing processes.

The book provides an in-depth exploration of the theory, implementation, and vast applications of the Discrete Element Method (DEM) and its coupling with Computational Fluid Dynamics (CFD) for simulating complex multiphase flows. Beginning with the core theoretical framework of DEM—covering particle kinematics, contact detection algorithms, and contact force models—the book systematically progresses to advanced topics. It provides detailed coverage of critical particle-fluid interaction mechanisms, robust CFD-DEM coupling schemes, and the integration of heat and mass transfer phenomena. The strategies for enabling large-scale simulations, including parallel computing, GPU acceleration, and coarse-graining techniques, are also included. The book stands apart through its unparalleled breadth of application-centric chapters. Readers will find dedicated sections on:•    Conventional and Advanced Reactors: Bubbling, spouted, and circulating fluidized beds, as well as magnetized and electrostatic systems.•    Dense Granular Systems: Particle packing, shear flow, silo/hopper discharge, and moving bed applications in chemical looping, pyrolysis, heat exchanger, and blast furnaces.•    Industrial Process Engineering: Pneumatic and screw conveyors, pump wear and flow dynamics, and mining operations in crushers, mills, screens, and chutes.•    Advanced Manufacturing: Pharmaceutical processes like milling, blending, granulation, tableting, and coating, as well as battery electrode calendering and recycling.•    Emerging Trends: The integration of machine learning and optimization strategies for complex multiphase flow systems.Bridging fundamental theory with cutting-edge practical advancements, Theory and Application of Discrete Element Method to Simulation of Multiphase Flows is an essential guide for students, engineers, and researchers seeking to model systems where particle dynamics are paramount.
