Journal ArticleDOI
Experimental and numerical study of fluidization and pressure drop of spherical and non-spherical particles in a model scale fluidized bed
TL;DR: In this paper, a laboratory scale fluidized bed was examined experimentally and numerically involving differently sized wooden Geldart-D particle shapes, and simulations were performed with a coupled DEM-CFD approach, which involves a drag force model that realizes for the particle shape and orientation.
Journal ArticleDOI
Direct numerical simulation of coupled fluid flow and heat transfer for single particles and particle packings by a LBM-approach
Harald Kruggel-Emden,B. Kravets,M.K. Suryanarayana,Raimondas Jasevičius,Raimondas Jasevičius +4 more
TL;DR: In this paper, lattice Boltzmann methods (LBM) have been used to solve the Navier-Stokes equations for particle/fluid interaction. But the results of the results were not validated with available state-of-the-art correlations.
Journal ArticleDOI
Investigation of the dust release from bulk material undergoing various mechanical processes using a coupled DEM/CFD approach
TL;DR: In this paper, a numerical approach to investigate the dust release from bulk solid during handling is presented, which relies on the Discrete Element Method (DEM) to describe the bulk particle motion coupled with Computational Fluid Dynamics (CFD) to model the gas and the dust phase as part of a multiphase framework.
Journal ArticleDOI
Comparison of particle-resolved DNS (PR-DNS) and non-resolved DEM/CFD simulations of flow through homogenous ensembles of fixed spherical and non‐spherical particles
B. Kravets,Daniel Schulz,Raimondas Jasevičius,Simon R. Reinecke,T. Rosemann,Harald Kruggel-Emden +5 more
TL;DR: In this article, the authors compared the accuracy of non-resolved Eulerian/Lagrangian simulations of static homogenous particle ensembles with direct numerical simulations performed with the Lattice-Boltzmann method (LBM).
Journal ArticleDOI
Simulation of Normal Impact of Ultrafine Silica Particle on Substrate
TL;DR: In this article, the normal impact of an ultrafine spherical silica particle with radius R = 0.6μm on the plane surface substrate was simulated numerically by applying DEM and the variation of the coefficient of restitution for a wide range of impact velocities up to 30m/s was investigated.
