DEM-CFD modeling and simulation of granular systems
Size reduction process is widely used in the chemical and pharmaceutical industries. Jetmill is one of the most commonly used tool for such processes due to advantages they over other mills such as low contamination and narrow product size distribution. However the efficiency of the jet milling process is very low, furthermore the jet-milling process is sensitive to many parameters such as feed...
متن کاملLarge Scale Landform Mapping Using Lidar DEM
In this study, LIDAR DEM data was used to obtain a primary landform map in accordance with a well-known methodology. This primary landform map was generalized using the Focal Statistics tool (Majority), considering the minimum area condition in cartographic generalization in order to obtain landform maps at 1:1000 and 1:5000 scales. Both the primary and the generalized landform maps were verifi...
متن کاملTitle: Simulation of Magnetic Suspensions for Hgms Using Cfd, Fem and Dem Modeling Simulation of Magnetic Particle Movement Using Fem and Cfd Simulation of Magnetic Suspensions for Hgms Using Cfd, Fem and Dem Modeling 2
7 Properties of magnetic suspensions depend on the fluid, the particles and the magnetic background field. 8 The simulation is aimed at understanding the influence of magnetic properties in High Gradient Magnetic 9 Separation processes. In HGMS magnetic particles are collected on magnetic wires for separation. External 10 magnetic forces are calculated or simulated using the Finite Element Meth...
متن کاملTans-scale Coupling in Multi-scale Simulation
The physics and mathematics involved in modeling of components of cardiovascular system is very different from that in many other engineering problems. For example, the blood flows in vessels with a deformable boundary (the viscoelastic walls of the vessel) that may require modeling of fluid and tissue interaction and for smaller arteries, the non-Newtonian nature of the blood requires special ...
متن کاملCFD technology for 3D simulation of large-scale hydrodynamic events and disasters
In this paper we discuss the basic components of the computational technology for the simulation of complex hydrodynamic events, such as a break of a dam, a wave pileup, a landslide, or a mud flow. The technology uses three-dimensional equations of fluid dynamics with free boundaries. The mathematical model is based on the Navier–Stokes equations with nonlinear defining relations between the st...
