Adaptive Finite Element Methods for Rigid Particulate Flow Problems
Subject of this work is the numerical simulation of the motion of rigid particles in an incompressible viscous or viscoelastic fluid. What makes this task especially challenging is the fact that two different physical models are coupled: The fluid motion is described by a system of partial …

Methods Development and Validation for Large Scale Simulations of Dense Particulate Flow systems in CFD-DEM Framework
… is widely used in simulating a large variety of particulate flow system. This Eulerian-Lagrangian technique tracks all the particles included in the system by the application of point mass models in their equation of motion. CFD-DEM is a more accurate (and more expensive) technique compared to an …

The hydrogeological structure of fault zones in poorly lithified sediment, Gulf of Corinth rift
… represented in two-dimensional numerical fluid-flow models in order to assess likely hydraulic impacts. Fault zone structure is found to be dominated by a mixed zone and differs to those previously reported. Two models of fault zone evolution are proposed for faults cutting: 1. Only poorly …

An investigation of the generation of acoustic emission from the flow of particulate solids in pipelines
The transport of particulate in a gas flow or pneumatic conveying system 1s widespread in many areas of industry, for example chemical, food processing, cement industries and transportation of pulverised coal in coal-fired power plants. However, a simple and reliable method for monitoring the flow …

Fault rock evolution and fluid flow in sedimentary basins
… involved in fault rock evolution and fluid flow associated with extensional faulting in upper crustal conditions. Intrabasinal fault rock evolution has been investigated in the Orcadian Basin, NE Scotland, which developed in Old Red Sandstone (ORS) times, soon after cessation of the …

Analysis of gas-solid multiphase flow systems in extreme flight environments using a one-way coupled DSMC-Lagrangian overlay-based computational framework
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-02-04 without embargo terms

Investigation of Momentum and Heat Transfer in Flow Past Suspensions of Non-Spherical Particles
… enables the calculation of the interstitial flow and pressure field surrounding each particle in suspension leading to the direct integration of fluid forces acting on each particle in the suspension. A substantial outcome of the research is the development of a new drag force correlation for …

Direct numerical simulation of viscoplastic particulate flows
… to modelling suspensions in viscoplastic fluid flows. Firstly, for fully resolved particle suspensions---regardless of the carrier fluid---the discretisation scheme must cope with disparate length scales at the particle boundaries and wider flow field. In this work we adopt the overset grid …

Analysis of hydrodynamic drag forces acting on suspended fine particle in porous media
An important class of flow and transport problems occurring in porous media involves the interactions between suspended fine particles and the moving fluid at Stokes limit. Historically, due to the complicated geometries of porous media, researchers have had to resort to simplifying assumptions to …
