TL;DR: In this article, the authors present a multi-purpose CFD-DEM framework to simulate coupled fluid-granular systems, where the motion of the particles is resolved by means of the Discrete Element Method (DEM), and the Computational Fluid Dynamics (CFD) method is used to calculate the interstitial fluid flow.
Abstract: We present a multi–purpose CFD–DEM framework to simulate coupled fluid–granular systems. The motion of the particles is resolved by means of the Discrete Element Method (DEM), and the Computational Fluid Dynamics (CFD) method is used to calculate the interstitial fluid flow. We first give a short overview over the DEM and CFD–DEM codes and implementations, followed by elaborating on the numerical schemes and implementation of the CFD–DEM coupling approach, which comprises two fundamentally different approaches, the unresolved CFD–DEM and the resolved CFD–DEM using an Immersed Boundary (IB) method. Both the DEM and the CFD–DEM approach are successfully tested against analytics as well as experimental data.

TL;DR: In this paper, the Vortex Method (VM) based boundary condition of Sergent (2002) was implemented in the general purpose CFD solver Fluent, and it was shown that the VM offers a relatively inexpensive and accurate way to generate random fluctuations representing a turbulent flow field at the inlet.
Abstract: The Vortex Method (VM) based boundary condition of Sergent (2002) was implemented in the general purpose CFD solver Fluent. It is shown that the VM offers a relatively inexpensive and accurate way to generate random fluctuations representing a turbulent flow field at the inlet. Since the generated velocity field is temporally and spatially correlated, it is a much more realistic representation of turbulence than the one obtained with a simple velocity distribution, using a random generator. Validations are reported for fully developed turbulent channel flow, pipe flow and separated hill flow.

TL;DR: In this article, the use of SPH to simulate a broad range of complex industrial fluid flow problems is discussed, including free surface fluid flow for the generation of digital content, geophysical flows such as volcanic lava flows and tsunamis, several types of die casting (gravity, high pressure and ingot casting), resin transfer molding and flow in porous media, mixing of particulates in liquid, pyrometallurgy and slurry flow in semi-autogenous grinding mills.
Abstract: SPH is a powerful mesh free method that is now able to solve very complex multi-physics flow and deformation problems in a broad number of fields. This paper concentrates on the use of SPH to simulate a broad range of complex industrial fluid flow problems. These include free surface fluid flow for the generation of digital content, geophysical flows such as volcanic lava flows and tsunamis, several types of die casting (gravity, high pressure and ingot casting), resin transfer moulding and flow in porous media, mixing of particulates in liquid, pyrometallurgy and slurry flow in semi-autogenous grinding mills. The strengths and weaknesses of SPH will be explored and future opportunities for using the method to make major modelling advances are discussed.

TL;DR: In this article, the Lattice Boltzmann equation (LBE) is integrated on unstructured grids and additional explicit schemes for time discretisation are proposed, with the aim of exactly locating solid boundaries.
Abstract: Further research on both theoretical and practical aspects of a previously defined finite-volume formulation to integrate the Lattice Boltzmann equation (LBE) on unstructured grids is presented. Moreover, additional explicit schemes for time discretisation are proposed. The method is tested on an impulsively started channel flow with the aim of exactly locating solid boundaries. Cavity flow simulations are used to measure the inaccuracies due to compressibility, grid and time discretisation effects. Finally, the proposed method has been tested against a laminar flow over a backward facing step in order to assess the effectiveness of open outlet boundary treatment.

TL;DR: In this article, the authors present a way of modelling turbulence in multiphase flows within the context of the Reynolds-Stress Model, which has been implemented in the general-purpose unstructured finite volume code Fluent V6.
Abstract: This paper presents a way of modelling turbulence in multiphase flows within the context of the Reynolds-Stress Model. The model has been implemented in the general-purpose unstructured finite volume code Fluent V6. Two multiphase turbulence approaches were considered: mixture and dispersed models. The mixture model solves the Reynolds-stress transport equations on the mixture level only. The dispersed approach solves the Reynolds-stress transport equations for the continuous phase, while the turbulence closure for the dispersed phases is achieved by an extension of the theory of dispersion of discrete particles by homogeneous turbulence. The dispersed model was used to calculate bubbly flow over a cylindrical back-step and the flow in an unbaffled stirred vessel. The mixture approach was used to calculate an industrially relevant cyclone flow.
