Book SynopsisBridging 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.Table of ContentsPreface MODELING OF GASIFIERS: OVERVIEW OF CURRENT DEVELOPMENTS Numerical Modeling in Engineering CFD-Based Modeling of Entrained Flow Gasifiers Benchmark Tests for CFD Modeling GASIFICATION OF SOLIDS: PAST, PRESENT AND FUTURE Introduction Historical Background Types of Gasification Reactors Trends in Gasifier Development Derived Challenges for Research MODELING OF MOVING PARTICLES: REVIEW OF BASIC CONCEPTS AND MODELS Introduction Soft-Sphere Model Hard-Sphere Model CD AND Nu CLOSURE RELATIONS FOR SPHERICAL AND NON-SPHERICAL PARTICLES Literature Review Model Description Code and Software Validation Porous Particles Non-Spherical Particles SINGLE PARTICLE HEATING & DRYING Nonporous Spherical Particle Heating in a Stream of Hot Air Heating of a Porous Particle Spherical Particle Drying in a Stream of Hot Air Conclusions UNSTEADY CHAR GASIFICATION/COMBUSTION Introduction Modeling Approach Numerics & Code Validation Advices for Beginners Analytical Methods INTERFACE TRACKING DURING CHAR PARTICLE GASIFICATION Interface and Porosity Tracking for a Moving Char Particle 3D Interface Tracking for a Porous Char Particle in a Kinetic Regime Conclusions PSEUDO-STEADY-STATE APPROACH FOR CARBON PARTICLE COMBUSTION/GASIFICATION Particle-Resolved CFD Simulations: Spherical Particles Particle-Resolved CFD Simulations: Nonspherical Particles Conclusions Setup of Heterogeneous Reactions in ANSYS FLUENT PORE-RESOLVED SIMULATION OF CHAR PARTICLE COMBUSTION/GASIFICATION Introduction Model Assumptions and Chemistry Small Porous Particle: 90 ?m Large Porous Particle: 2mm 3D Simulations under Gasification Conditions Conclusions SUBGRID MODELS FOR PARTICLE DEVOLATILIZATION-COMBUSTION-GASIFICATION Subgrid Model for the Devolatilization/Combustion of a Moving Coal Particle Novel Intrinsic Submodel for Gasification of a Moving Char Particle NEW FRONTIERS AND CHALLENGES IN GASIFICATION TECHNOLOGIES Introduction Trends in Gasifier Design Future Gasifier Simulations Index
