Available in PDF, EPUB and Kindle. Book excerpt: An experiment was conducted to investigate the development of longitudinal stripes of granular particles due to instabilities in particle suspension flow. Research was conducted to characterize environmental phenomena related to granular flows, namely avalanches, mudslides, and the movement of glaciers. Results show the stripes were found to appear with a particle concentration of 10% by volume at angles of 20 degrees, at a particle concentration of 20% and 30% by volume at 20, 30, and 40 degrees, and at a particle concentration for 40% by volume at 20 degrees. The application of a shear stress intensified the development of the instabilities, and in experimental trials where stripes were not initially seen, the application of a shear stress was able to induce the fluid to develop the instability.

Download or read book Flow of Particulate Suspensions Through Constrictions written by Somnath Mondal and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle-laden flows occur in a variety of natural and industrial situations. As particulate suspensions flow through a medium, particles are often retained at constrictions such as pore throats, outlets or orifices. This occurs not only with oversized particles, but also with particles smaller than the constriction. For instance, jams are caused by the formation of particle bridges/arches when several particles attempt to flow through a constriction simultaneously. In many instances the success of an operation depends on our ability to either ensure or stop the flow of particles in the flow stream. Managing the flow of sand into wellbores during hydrocarbon production from poorly consolidated sandstone reservoirs, also referred to as sand control, is one such application in the oil and gas industry. This dissertation presents a multi-pronged effort at modeling the flow of granular suspensions of different concentrations, and through pore openings of different shapes, with two main objectives: (1) predicting the mass and size-distribution of the particles that are produced before jamming, and (2) investigating the underlying factors that influence the onset and stability of particle arches. Since, the dominant interactions and retention mechanisms are concentration dependent, we divided particulate suspensions into three groups based on the volumetric particle concentration ([phi]). High-concentration suspension flows ([phi]>~50%) are dominated by particle-particle interactions. We modeled polydisperse sand packs flowing through screens with rectangular and woven-square openings using 3D discrete element method (DEM). Simulations were validated against experimental data for a wide range of screen opening and sand size distributions. From the experiments and DEM simulations, a new scaling relation is identified, in which the number of different sized particles produced before retention follows a power-law correlation with the particle-to-outlet size ratio. This correlation is explained with a simple probabilistic model of bridging in polydisperse systems and a particle-size dependent jamming probability calculated from experimental data. A new method is presented to estimate the mass and size distribution of the produced solids through screens. The method uses the entire particle size distribution (PSD) of the formation sand, is validated with experimental data and numerical simulations, and provides more quantitative and accurate predictions of screen performance compared to past methods. It is also found that the stability of particle arches is compromised when adjacent outlets are less than three particle diameters away from each other. Low-concentration suspension flows ([phi]
Download or read book Particulate Gravity Currents written by W. D. McCaffrey and published by John Wiley & Sons. This book was released on 2009-03-05 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume arises from the conference Sediment Transport andDeposition by Particulate Gravity Currents held in the UK in 1998.The field of particulate gravity currents ranges from turbiditycurrents in the oceans, lakes and reservoirs to pyroclastic densitycurrents and avalanches, debris flows and lahars, grainflows,powder snow avalanches, effluent dispersal and ancient gravitycurrent deposits. Although the sub-division of particulate gravity currents intodiscrete sub-categories (such as grain flows, turbidity currents ordebris flows) provides a convenient descriptive shorthand, itundermines the sense of process continuum needed to describe manynatural flows. The structure of this volume reflects an integrativeaim, with papers grouped by research approach. The first section ofthe book contains six papers on theoretical and numerical modellingof a range of flow types. The following four papers are focusedupon combined theoretical and experimental modelling approaches.The next section contains four papers describing experimentalmodelling and the final section includes five papers detailingfield-based studies. The volume stands as a testament to the broad range of researchcarried out on particulate gravity currents, and hints at theenhanced rate of progress that is likely to be achieved throughfurther integrated studies.

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.
