Download or read book Discrete Particle Simulation Techniques for the Analysis of Colliding and Flowing Particulate Media written by Debanjan Mukherjee and published by . This book was released on 2013 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flowing particulate media are ubiquitous in a wide spectrum of applications that include transport systems, fluidized beds, manufacturing and materials processing technologies, energy conversion and propulsion technologies, sprays, jets, slurry flows, and biological flows. The discrete nature of the media, along with their underlying coupled multi-physical interactions can lead to a variety of interesting phenomena, many of which are unique to such media - for example, turbulent diffusion and preferential concentration in particle laden flows, and soliton like excitation patterns in a vibrated pile of granular material. This dissertation explores the utility of numerical simulations based on the discrete element method and collision driven particle dynamics methods for analyzing flowing particulate media. Such methods are well-suited to handle phenomena involving particulate, granular, and discontinuous materials, and often provide abilities to tackle complicated physical phenomena, for which pursuing continuum based approaches might be difficult or sometimes insufficient. A detailed discussion on hierarchically representing coupled, multi-physical phenomena through simple models for underlying physical interactions is presented. Appropriate physical models for mechanical contact, conductive and convective heat exchange, fluid-particle interactions, adhesive and near-field effects, and interaction with applied electromagnetic fields are presented. Algorithmic details on assembling the interaction models into a large-scale simulation framework have been elaborated with illustrations. The assembled frameworks were used to develop a computer simulation library (named `Software Library for Discrete Element Simulations' (SLIDES) for the sake of reference and continued future development efforts) and aspects of the architecture and development of this library have also been addressed. This is an object-oriented discrete particle simulation library developed in Fortran capable of performing fully 3D simulations of particulate systems. The utility and effectiveness of the developed simulation frameworks have been demonstrated using two case studies. The first study is on the analysis of the high velocity impact of stream of particles on a porous layer of material, which is a problem of interest in the analysis of erosive wear of manufactured surface coatings. The second case-study is based on the deposition of flowing particulate spray on a target surface, which is a problem of interest in the analysis of particulate deposition-based manufacturing processes. In both cases, the aspect of extracting important information on system behavior from the collective dynamics of the particulate media has been outlined. For the first case, this involved a characterization of material damage due to impact generated stresses, and for the second case, this involved analysis of adhesion and deposited coating properties.

This book was released on 2001 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) A survey of the representations used in numerical implementations is fol- lowed by an analysis of model complexity as new components are added. The numerical implementation of a split composition distribution method for multicomponent systems is presented, and the solution is verified against analytical results. Numerical stability requirements under varying growth rate laws are used to develop new scaling methods which enable the description of particles over many orders of magnitude in size. Numerous examples are presented to illustrate the utility of these methods and to familiarize the reader with the development and manipulations of the representations, governing equations, and numerical implementations of population balance systems.

This book was released on 2014 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The air quality near agricultural activities such as tilling, plowing, harvesting, and manure application is of main concern because they release fine particulate matter into the atmosphere. These releases are modeled as area-sources in the air quality modeling research. None of the currently available dispersion models relate and incorporate physical characteristics and meteorological conditions for modeling the dispersion and deposition of particulates emitting from such area-sources. This knowledge gap was addressed by developing the advanced analytical and numerical methods for modeling the dispersion of particulate matter. The development, application, and evaluation of new dispersion modeling methods are discussed in detail in this dissertation. In the analytical modeling, a ground-level area source analytical dispersion model known as particulate matter deposition - PMD was developed for predicting the concentrations of different particle sizes. Both the particle dynamics (particle physical characteristics) and meteorological conditions which have significant effect on the dispersion of particulates were related and incorporated in the PMD model using the formulations of particle gravitational settling and dry deposition velocities. The modeled particle size concentrations of the PMD model were evaluated statistically after applying it to particulates released from a biosolid applied agricultural field. The evaluation of the PMD model using the statistical criteria concluded effective and successful inclusion of dry deposition theory for modeling particulate matter concentrations. A comprehensive review of analytical area-source dispersion models, which do not account for dry deposition and treat pollutants as gases, was conducted and determined three models - the Shear, the Parker, and the Smith. A statistical evaluation of these dispersion models was conducted after applying them to two different field data sets and the statistical results concluded that the Shear model performed the best out of the three dispersion models. The algorithms of each dispersion model were analyzed and it was determined that the best performance of the Shear model was due to incorporation of a variation of wind speed and vertical eddy diffusivity (atmospheric turbulence) with the height above ground surface. A new methodology was developed using computational fluid dynamics (CFD) - FLUENT for the numerical dispersion modeling of particulate matter emitting from an area-source (biosolids applied agricultural field). The discrete phase model (Lagrangian -Eulerian approach) was used in combination with each of the four turbulence models: Standard ke (ke), Realizable ke (Rke), Standard k¿ (k¿), and Shear-stress transport k-¿ (SST) to predict particulate matter size concentrations for distances downwind of the agricultural field. In this modeling approach, particulates were simulated as discrete phase and air as continuous phase. The discrete phase model accounted for the effects of atmospheric turbulence and drag force which is dependent on particle physical characteristics (diameter, density, and velocity), gravitational velocity, and air viscosity for predicting the trajectories of particles. The modeled particulate matter concentrations were compared statistically with their corresponding field study observations to evaluate the performance of proposed CFD model using the four turbulence models. The statistical analysis concluded that among four turbulence models, the discrete phase model when used with Rke performed the best in predicting particulate matter concentrations for low (u 2 m/s) and medium (2

Download or read book Dynamics of Charged Particulate Systems written by Tarek I. Zohdi and published by Springer. This book was released on 2012-04-05 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this monograph is to provide a concise introduction to the dynamics of systems comprised of charged small-scale particles. Flowing, small-scale, particles ("particulates'') are ubiquitous in industrial processes and in the natural sciences. Applications include electrostatic copiers, inkjet printers, powder coating machines, etc., and a variety of manufacturing processes. Due to their small-scale size, external electromagnetic fields can be utilized to manipulate and control charged particulates in industrial processes in order to achieve results that are not possible by purely mechanical means alone. A unique feature of small-scale particulate flows is that they exhibit a strong sensitivity to interparticle near-field forces, leading to nonstandard particulate dynamics, agglomeration and cluster formation, which can strongly affect manufactured product quality. This monograph also provides an introduction to the mathematically-related topic of the dynamics of swarms of interacting objects, which has gained the attention of a number of scientific communities. In summary, the following topics are discussed in detail: (1) Dynamics of an individual charged particle, (2) Dynamics of rigid clusters of charged particles, (3) Dynamics of flowing charged particles, (4) Dynamics of charged particle impact with electrified surfaces and (5) An introduction to the mechanistic modeling of swarms. The text can be viewed as a research monograph suitable for use in an upper division undergraduate or first year graduate course geared towards students in the applied sciences, mechanics and mathematics that have an interest in the analysis of particulate materials.
