Abstract: |
In this work the erosion and sedimentation of a packed bed of spheres in the vicinity of an massive obstacle is studied. The changing topology is accounted for by an Immersed Boundary (IB) method and an Arbitrary Lagrangian Eulerian (ALE) grid deformation approach. While in the first case the surface of the packed bed is tracked through a fixed computational grid the ALE approach addresses the deformation of the computational grid at the bed’s surface. The particle transport itself is described by an Eulerian particle model of the commercial computational fluid dynamics (CFD) solver FLUENT. Furthermore, particle entrainment due to fluid shear, particle rebound after impact, fluid momentum loss due to entrained particles as well as particle sedimentation and accumulation are addressed by several sub-models that are based on literature. Finally, both modeling approaches deliver reasonable and comparable results with respect to the final erosion pattern. Moreover, the numerical results are opposed to a wind tunnel experiment showing suitable correlation with measurement. |

General Note: |
The International Conference on Multiphase Flow (ICMF) first was held in Tsukuba, Japan in 1991 and the second ICMF took place in Kyoto, Japan in 1995. During this conference, it was decided to establish an International Governing Board which oversees the major aspects of the conference and makes decisions about future conference locations. Due to the great importance of the field, it was furthermore decided to hold the conference every three years successively in Asia including Australia, Europe including Africa, Russia and the Near East and America. Hence, ICMF 1998 was held in Lyon, France, ICMF 2001 in New Orleans, USA, ICMF 2004 in Yokohama, Japan, and ICMF 2007 in Leipzig, Germany. ICMF-2010 is devoted to all aspects of Multiphase Flow. Researchers from all over the world gathered in order to introduce their recent advances in the field and thereby promote the exchange of new ideas, results and techniques. The conference is a key event in Multiphase Flow and supports the advancement of science in this very important field. The major research topics relevant for the conference are as follows: Bio-Fluid Dynamics; Boiling; Bubbly Flows; Cavitation; Colloidal and Suspension Dynamics; Collision, Agglomeration and Breakup; Computational Techniques for Multiphase Flows; Droplet Flows; Environmental and Geophysical Flows; Experimental Methods for Multiphase Flows; Fluidized and Circulating Fluidized Beds; Fluid Structure Interactions; Granular Media; Industrial Applications; Instabilities; Interfacial Flows; Micro and Nano-Scale Multiphase Flows; Microgravity in Two-Phase Flow; Multiphase Flows with Heat and Mass Transfer; Non-Newtonian Multiphase Flows; Particle-Laden Flows; Particle, Bubble and Drop Dynamics; Reactive Multiphase Flows |
