Modeling particle-fluid interaction in a coupled CFD-DEM framework

Parallel Open Source Cfd-dem for Resolved Particle-fluid Interaction

In the following paper we present a parallelized resolved method for the simulation of the dynamics of immersed bodies within fluids. The algorithm uses the so called Fictitious Domain Method (FDM) and combines the Lagrangian Discrete Element Method (DEM) for the tracking of the bodies and a Computational Fluid Dynamics (CFD) method for the calculation of the flow and pressure field of the flui...

Coupling CFD-DEM with dynamic meshing: A new approach for fluid-structure interaction in particle-fluid flows

Article history: Received 2 August 2017 Received in revised form 29 October 2017 Accepted 13 November 2017 Available online 21 November 2017 Many important engineering applications involve the interaction of free-moving objects with dispersed multiphase flows, however due to the challenge and complexity ofmodelling these systems,modelling approaches remain very limited and very few studies have...

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...

CFD-Calculation of Fluid Flow in a

An accurate description of the fluid flow and heat transfer within a Pressurized Water Reactor (PWR), for the safety analysis and reactor performance is always desirable. In this paper a mathematical model of the fundamental physical phenomena which are associated to a typical PWR is presented. The mathematical model governs the fluid dynamics in the reactor. Using commercial software CFX, a co...
