Book Synopsis Collective Dynamics of Particles by : Cristian Marchioli
Download or read book Collective Dynamics of Particles written by Cristian Marchioli and published by Springer. This book was released on 2017-02-21 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book surveys the state-of-the-art methods that are currently available to model and simulate the presence of rigid particles in a fluid flow. For particles that are very small relative to the characteristic flow scales and move without interaction with other particles, effective equations of motion for particle tracking are formulated and applied (e.g. in gas-solid flows). For larger particles, for particles in liquid-solid flows and for particles that interact with each other or possibly modify the overall flow detailed model are presented. Special attention is given to the description of the approximate force coupling method (FCM) as a more general treatment for small particles, and derivations in the context of low Reynolds numbers for the particle motion as well as application at finite Reynolds numbers are provided. Other topics discussed in the book are the relation to higher resolution immersed boundary methods, possible extensions to non-spherical particles and examples of applications of such methods to dispersed multiphase flows.

Book Synopsis Motion of a Spherical Particle in a Turbulent Flow by : Prem K. Khosla
Download or read book Motion of a Spherical Particle in a Turbulent Flow written by Prem K. Khosla and published by . This book was released on 1973 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motion of a particle in a turbulent fluid is examined. A relaxation process is introduced to incorporate the difference in particle and the fluid diffusivities. The effect of the reduction in the diffusivity ratio, changes in temperature and density of the fluid, and the presence of various size particles are examined. It is shown that each of these factors may limit the applicability of the LDV to low Mach number and low frequency turbulence. (Author).
Book Synopsis An Experimental Study of Solid Particle Motion in a Turbulent Liquid Pipe Flow by : James Bradley Young
Download or read book An Experimental Study of Solid Particle Motion in a Turbulent Liquid Pipe Flow written by James Bradley Young and published by . This book was released on 1989 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of the motion of 100 micron diameter glass and stainless steel spheres in a fully developed turbulent liquid pipe flow was conducted. Furthermore, the liquid, water, was directed vertically downward through a 5.08 cm inside diameter plexiglas tube. One goal was to measure the turbulence properties of the particles in the r-$theta$ plane with a previously developed axial viewing photographic technique. Another goal was to determine the effects of the inherent inhomogeneities of turbulent pipe flow on the results. Several particle turbulence properties were measured. Radial direction Lagrangian and Eulerian particle diffusion coefficients were obtained at Reynolds numbers (based on bulk velocity and pipe diameter) ranging from 15,700 to 141,000. Radial and azimuthal direction particle turbulence intensity profiles for both particles were obtained at Re = 16,000 and 72,000. The technique also permitted the radial and azimuthal direction particle acceleration to be measured. A new phenomenon was discovered which is the result of the inhomogeneities of turbulent pipe flow. It was found that under certain conditions, the particles that diffuse to the pipe wall may get temporarily or permanently trapped there. They get trapped in a patterned manner as well. Inhomogeneities were also found to affect the measured radial direction particle concentration and average velocity profiles, but only under certain conditions.
Book Synopsis Molecular and Particle Modelling of Laminar and Turbulent Flows by : Donald Greenspan
Download or read book Molecular and Particle Modelling of Laminar and Turbulent Flows written by Donald Greenspan and published by World Scientific. This book was released on 2005 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulence is the most fundamental and, simultaneously, the most complex form of fluid flow. However, because an understanding of turbulence requires an understanding of laminar flow, both are explored in this book.Groundwork is laid by careful delineation of the necessary physical, mathematical, and numerical requirements for the studies which follow, and include discussions of N-body problems, classical molecular mechanics, dynamical equations, and the leap frog formulas for very large systems of second order ordinary differential equations.Molecular systems are studied first in both two and three dimensions. Extension into the large is also of great interest, and it is for this purpose that we develop particle mechanics, which uses lump massing of molecules. All calculations are limited to a personal scientific computer, so that the methods can be utilized readily by others.

Coverage also treats in detail problems of physical simulation of turbulent gas flows which carry solid particles.

Book Synopsis Dynamics of Non-spherical Particles in Turbulence by : Luis Blay Esteban
Download or read book Dynamics of Non-spherical Particles in Turbulence written by Luis Blay Esteban and published by . This book was released on 2020 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book studies the dynamics of 2D objects moving through turbulent fluids. It examines the decay of turbulence over extended time scales, and compares the dynamics of non-spherical particles moving through still and turbulent fluids. The book begins with an introduction to the project, its aims, and its relevance for industrial applications. It then discusses the movement of planar particles in quiescent fluid, and presents the numerous methodologies used to measure it. The book also presents a detailed analysis of the falling style of irregular particles, which makes it possible to estimate particle trajectory and wake morphology based on frontal geometry. In turn, the book provides the results of an analysis of physically constrained decaying turbulence in a laboratory setting. These results suggest that large-scale cut-off in numerical simulations can result in severe bias in the computed turbulent kinetic energy for long waiting times. Combining the main text with a wealth of figures and sketches throughout, the book offers an accessible guide for all engineering students with a basic grasp of fluid mechanics, while the key findings will also be of interest to senior researchers.
