Available in PDF, EPUB and Kindle. Book excerpt: The relatively recent increase in computational power available for mathematical modeling and simulation raises the possibility that modern numerical methods can play a significant role in the analysis of complex particulate flows. An Introduction to Modeling and Simulation of Particulate Flows focuses on basic models and physically based computational solution strategies for the direct and rapid simulation of flowing particulate media. Its emphasis is primarily on fluidized dry particulate flows in which there is no significant interstitial fluid, although fully coupled fluid-particle systems are discussed as well. An introduction to basic computational methods for ascertaining optical responses of particulate systems also is included. The successful analysis of a wide range of applications requires the simulation of flowing particulate media that simultaneously involves near-field interaction and contact between particles in a thermally sensitive environment. These systems naturally occur in astrophysics and geophysics; powder processing pharmaceutical industries; bio-, micro- and nanotechnologies; and applications arising from the study of spray processes involving aerosols, sputtering, and epitaxy. Audience: written for computational scientists, numerical analysts, and applied mathematicians, it will be of interest to civil and mechanical engineers and materials scientists. It is also suitable for first-year graduate students in the applied sciences, engineering, and applied mathematics who have an interest in the computational analysis of complex particulate flows.

Available in PDF, EPUB and Kindle. Book excerpt: The COVID-19 pandemic that started in 2019-2020 has led to a gigantic increase in modeling and simulation of infectious diseases. There are numerous topics associated with this epoch-changing event, such as (a) disease propagation, (b) transmission, (c) decontamination, and (d) vaccines. This is an evolving field. The targeted objective of this book is to expose researchers to key topics in this area, in a very concise manner. The topics selected for discussion have evolved with the progression of the pandemic. Beyond the introductory chapter on basic mathematics, optimization, and machine learning, the book covers four themes in modeling and simulation infectious diseases, specifically: Part 1: Macroscale disease propagation, Part 2: Microscale disease transmission and ventilation system design, Part 3: Ultraviolet viral decontamination, and Part 4: Vaccine design and immune response. It is important to emphasize that the rapid speed at which the simulations operate makes the presented computational tools easily deployable as digital twins, i.e., digital replicas of complex systems that can be inexpensively and safely optimized in a virtual setting and then used in the physical world afterward, thus reducing the costs of experiments and also accelerating development of new technologies.

Available in PDF, EPUB and Kindle. Book excerpt: Multiphysics Modelling of Fluid-Particulate Systems provides an explanation of how to model fluid-particulate systems using Eulerian and Lagrangian methods. The computational cost and relative merits of the different methods are compared, with recommendations on where and how to apply them provided. The science underlying the fluid-particulate phenomena involves computational fluid dynamics (for liquids and gases), computational particle dynamics (solids), and mass and heat transfer. In order to simulate these systems, it is essential to model the interactions between phases and the fluids and particles themselves. This book details instructions for several numerical methods of dealing with this complex problem. This book is essential reading for researchers from all backgrounds interested in multiphase flows or fluid-solid modeling, as well as engineers working on related problems in chemical engineering, food science, process engineering, geophysics or metallurgical processing. Provides detailed coverage of Resolved and Unresolved Computational Fluid Dynamics - Discrete Element Method (CFD-DEM), Smoothed Particle Hydrodynamics, and their various attributes Gives an excellent summary of a range of simulation techniques and provides numerical examples Starts with a broad introduction to fluid-particulate systems to help readers from a range of disciplines grasp fundamental principles

Available in PDF, EPUB and Kindle. Book excerpt: Compressed sensing is a relatively recent area of research that refers to the recovery of high-dimensional but low-complexity objects from a limited number of measurements. The topic has applications to signal/image processing and computer algorithms, and it draws from a variety of mathematical techniques such as graph theory, probability theory, linear algebra, and optimization. The author presents significant concepts never before discussed as well as new advances in the theory, providing an in-depth initiation to the field of compressed sensing. An Introduction to Compressed Sensing contains substantial material on graph theory and the design of binary measurement matrices, which is missing in recent texts despite being poised to play a key role in the future of compressed sensing theory. It also covers several new developments in the field and is the only book to thoroughly study the problem of matrix recovery. The book supplies relevant results alongside their proofs in a compact and streamlined presentation that is easy to navigate. The core audience for this book is engineers, computer scientists, and statisticians who are interested in compressed sensing. Professionals working in image processing, speech processing, or seismic signal processing will also find the book of interest.

Available in PDF, EPUB and Kindle. Book excerpt: Particulate flows exist in a wide range of engineering applications such as drilling and completion operations--from hole-cleaning to well stimulation to sand control. The operations involving particulate flows typically focus on achieving either (1) efficient particle transport or (2) effective particle retention, both of which require a deep understanding of particulate flow behavior under different flow conditions. This dissertation presents novel approaches for modeling particulate transport with the intent to optimize operational efficiency in specific important oilfield applications. The first half of this dissertation focuses on modeling particle transport inside a wellbore. A typical example of such an operation is the pumping of proppant/diverter slurry during a hydraulic fracturing treatment. During the treatment, the particles are moved in a carrier fluid from the wellbore through the perforations and finally into the fractures. The motion of the particles is primarily influenced by the interactions between the fluid phase and the solid phase, and therefore, a precise description of the particle-fluid interactions is essential for modeling the process. The coupling of computational fluid dynamics with the discrete element method (CFD-DEM) approach is adopted for this task. The investigation begins with evaluating the particle transport efficiency (PTE) through a perforation in a horizontal wellbore under various downhole flow conditions. A comprehensive study on the effect of casing, perforation, solid, and fluid properties on PTE is presented. On the basis of the study, empirical PTE correlations are derived and integrated into a multi-cluster hydraulic fracturing model to simulate proppant/diverter transport at a wellbore scale. Simulation results show that because of its high inertia, the transport of proppant is generally much more difficult than the transport of carrier fluid through the perforations. By assuming a simple jamming criterion based on local proppant concentration near the perforations, the heel-biased treatment distribution commonly observed in the field can be accurately reproduced by the model. Recommendations on fracturing job design for promoting an even treatment distribution are also discussed. The second half of the dissertation focuses on modeling particle retention in sand control completions with a special focus on multi-layered metal-mesh screens and gravel packs. A DEM-based approach is developed to evaluate the pore throat size distribution (PoSD) of the sand-retention media. Simulation results show that for a multi-layer plain square mesh (PSM) screen, the overlap, alignment, and relative pore size between individual layers all have a significant impact on the screen's PoSD. In contrast, only the intra-layer overlap of the filter is important for controlling the PoSD of a multi-layered plain Dutch weave (PDW) screen. For gravel packs, simulation results show that the largest and smallest pore throat sizes are about 1/5 and 1/10 of the effective gravel size for typical gravel sizes used in the field. By using the computed PoSD as an input, an analytical model and a Monte-Carlo model are developed to predict sand production through gravel packs. The modeled PoSD and sand production agree reasonably well with field observations and experimental data. Our approach enables completion engineers to tailor gravel pack designs for different combinations of formation sand size distribution (PSD) and wellbore geometry in a cost-efficient manner
