Download or read book Granular Gases written by Thorsten Pöschel and published by Springer Science & Business Media. This book was released on 2001-02-27 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Granular Gases" are diluted many-particle systems in which the mean free path of the particles is much larger than the typical particle size, and where particle collisions occur dissipatively. The dissipation of kinetic energy can lead to effects such as the formation of clusters, anomalous diffusion and characteristic shock waves to name but a few. The book is organized as follows: Part I comprises the rigorous theoretical results for the dilute limit. The detailed properties of binary collisions are described in Part II. Part III contains experimental investigations of granular gases. Large-scale behaviour as found in astrophysical systems is discussed in Part IV. Part V, finally, deals with possible generalizations for dense granular systems.

Download or read book Fundamentals of Gas Particle Flow written by G Rudinger and published by Elsevier. This book was released on 2012-12-02 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Gas-Particle Flow is an edited, updated, and expanded version of a number of lectures presented on the “Gas-Solid Suspensions course organized by the von Karman Institute for Fluid Dynamics. Materials presented in this book are mostly analytical in nature, but some experimental techniques are included. The book focuses on relaxation processes, including the viscous drag of single particles, drag in gas-particles flow, gas-particle heat transfer, equilibrium, and frozen flow. It also discusses the dynamics of single particles, such as particles in an arbitrary flow, in a rotating gas, in a Prandtl-Meyer expansion, and in an oscillating flow. The remaining chapters of the book deal with the thermodynamics of gas-particle mixtures, steady flow through ducts, pressure waves, gas-particle jets, boundary layer, and momentum transfer. The experimental techniques included in this book present the powder feeders, the instrumentation on particle flow rate, velocity, concentration and temperature, and the measurement of the particle drag coefficient in a shock tube.

Download or read book Instability and Segregation in bounded Gas Particle and Granular Flows written by Xue Liu and published by VDM Publishing. This book was released on 2008 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid-particle and granular flows exhibit rather complex behavior, for example, the occurrence of bubbles and clusters in gas-particle flows, and clogging and size segregation in granular flows. This work is to advance our understanding of granular and gas particle flows using computational simulations. In gas-particle fluidized beds, confined between parallel solid walls, non-uniform solids distribution is observed and the flow profiles are strongly related to the physical and operating parameters, such as particle inelasticity, gravity, bed width and mean solids fraction. A stability analysis has been carried out to investigate the instabilities in gas-particle flows and the generation of cluster, bubbles or streamers in gas-fluidized beds. For boundary driven and body-force-driven granular flows and gas-particle fluidized beds with polydisperse particle mixtures, the particle species segregation is enhanced with a decrease in the system elasticity, an increase in the average solids fraction or an increase in the size ratio, due to the competition of diffusion forces. The distribution of granular energy and its effect on the segregation is also considered in this work.

Book excerpt: Back Cover Text: This book addresses the study of the gaseous state of granular matter in the conditions of rapid flow caused by a violent and sustained excitation. In this regime, grains only touch each other during collisions and hence, kinetic theory is a very useful tool to study granular flows. The main difference with respect to ordinary or molecular fluids is that grains are macroscopic and so, their collisions are inelastic. Given the interest in the effects of collisional dissipation on granular media under rapid flow conditions, the emphasis of this book is on an idealized model (smooth inelastic hard spheres) that isolates this effect from other important properties of granular systems. In this simple model, the inelasticity of collisions is only accounted for by a (positive) constant coefficient of normal restitution. The author of this monograph uses a kinetic theory description (which can be considered as a mesoscopic description between statistical mechanics and hydrodynamics) to study granular flows from a microscopic point of view. In particular, the inelastic version of the Boltzmann and Enskog kinetic equations is the starting point of the analysis. Conventional methods such as Chapman-Enskog expansion, Grad’s moment method and/or kinetic models are generalized to dissipative systems to get the forms of the transport coefficients and hydrodynamics. The knowledge of granular hydrodynamics opens up the possibility of understanding interesting problems such as the spontaneous formation of density clusters and velocity vortices in freely cooling flows and/or the lack of energy equipartition in granular mixtures. Some of the topics covered in this monograph include: Navier-Stokes transport coefficients for granular gases at moderate densities Long-wavelength instability in freely cooling flows Non-Newtonian transport properties in granular shear flows Energy nonequipartition in freely cooling granular mixtures Diffusion in strongly sheared granular mixtures Exact solutions to the Boltzmann equation for inelastic Maxwell models
Download or read book Granular Materials written by Michael Sakellariou and published by BoD – Books on Demand. This book was released on 2017-09-06 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents basic notions and fundamental properties of granular materials covering a wide spectrum of granular material mechanics. The granular materials may behave as fluids or solids or both. The grain size may span from microscopic to macroscopic scale. From the wet sand effect, Reynolds inspired in 1885 the notion of granular universe introducing the term "dilatancy." Bak, Tan, and Wisenfeld (1987, 1988) used the sand pile as a representative model of complex systems. In this collection of chapters, granular dynamics, granular flow from dilute to jammed states, dynamics of granular gas in microgravity, particle jetting induced by impulsive loadings, particle migration phenomena in embankment dams, and the grading entropy-based criteria of granular materials and filters are presented.

Download or read book Instability and Segregation in Bounded Gas particle Fluidized Beds and Granular Flows written by Xue Liu and published by . This book was released on 2006 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finally, we extend our work to investigate the steady state solutions of boundary-driven and body-force-driven granular flows and gas-particle fluidized beds with a bi-disperse particle mixture. Granular energy equipartition breaks down with an increase in the system inelasticity and the mass ratio, whereas the effect of the size ratio is very small if the two particle species have the same mass. The segregation of total particles and each individual particle species is enhanced when the effect of non-equipartition of granular energy is considered. The species segregation is enhanced with a decrease in the system elasticity, an increase in the average solids fraction or an increase in the size ratio, due to the competition of three diffusion forces: the thermal diffusion force, the ordinary diffusion force and the pressure diffusion force. For gas-particle fluidized beds and granular flows in a channel, we find that for the kinetic theory models used in the present study, the solids fraction and the granular temperature profiles are quite similar.
