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...
متن کاملParallel 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...
متن کاملFluid-Structure Interaction in Internal Physiological Flows
We provide a selective review of recent progress in the analysis of several physiological and physiologically inspired fluid-structure interaction problems, our aimbeing to explain the underlying physicalmechanisms that cause the observed behaviors. Specifically, we discuss recent studies of self-excited oscillations in collapsible tubes, focusing primarily on studies of an idealized model syst...
متن کاملA Strong Coupling Scheme for Fluid-structure Interaction Problems in Viscous Incompressible Flows
In the present paper an embedded-boundary formulation that is applicable to fluid structure interaction problems is presented. The Navier-Stokes equations for incompressible flow are solved on a fixed grid which is not aligned with the body. A corotational formulation is used to describe the dynamics of a body that moves through the fixed grid undergoing large-angle/large-displacement rigid bod...
متن کاملA Parallel, Black-box Coupling Algorithm for Fluid-structure Interaction
The simulation of multi-physics scenarios, in particular fluid-structure interaction has gained more and more importance in the last years due to increasing accuracy requirements for a large range of applications from biomedical fields to technical design problems. At the same time, this type of simulation has become feasible due to the increased computing power of modern supercomputers. Note t...
