A one-way coupled DEM-CFD scheme to mode free-surface flows in tumbling mills
… two fluid phases (for slurry and air) and one solid phase (for the charge). Existing 3-phase work makes use of a purely particle-based description, coupling the discrete element method (DEM) for the solids with smoothed particle hydrodynamics (SPH) for the fluids. This work is the first …

Numerical investigation of airflow and aerosol deposition characteristics within human airways
Aerosolized drug delivery in human airways is typically used for the treatment of several pulmonary diseases. In this study, large-eddy simulation (LES) is used for the numerical investigation of the airflow and the aerosol deposition characteristics within the upper human airways. LES is performed …

A lattice boltzmann/s n framework for coupled heat transfer and neutron transport problems
Nuclear reactors are complex, coupled, multi-physics and multi-scale systems. There are usually two approaches — loose coupling and tight coupling — to solve coupled mathematical equations describing a multi-physics system. The major advantage of loose coupling is to allow separately validated …

Modeling and Sensitivity Analysis for Trace Gas Sensors
… gases. Existing models of QEPAS sensors employ one-way coupling from the fluid to the structure that requires prior experimental measurements of the damping of the QTF due to its motion in the viscous fluid. We study an improved two-way coupled model that is based on a Helmholtz system of …

Multi-Scale Localized Perturbation Method for Geophysical Fluid Flows
… decomposed into background and perturbation components, then assumptions are made about the evolution of these components within the context of an environmental flow in order to close the system. Once closed, the original governing equations become a set of one-way coupled governing equations …

Coupled geomechanics and transient multiphase flow at fracture-matrix interface in tight reservoirs.
… models have been validated against Berea Sandstone experimental data. Two separate numerical models have been developed with the aim to identify the most appropriate modelling technique for accurate numerical predictions of multiphase flow in naturally-fractured tight reservoirs. These two …

Effects of internal waves on low frequency, long range, acoustic propagation in the deep ocean
… scales of sound speed fluctuations one might expect in this region of the North Pacific for both internal-wave band fluctuations and mesoscale band fluctuations. The thesis then presents a detailed analysis of the low frequency, broadband sound arrivals obtained in the North Pacific …

Multiscale analysis of localized, nonlinear, three-dimensional thermo-structural effects
… (G/XFEM) for analyzing three-dimensional solid, coupled physics problems exhibiting localized heating and thermomechanical effects. The method is based on the GFEM with global–local enrichment functions (GFEMgl), which involves the solution of interdependent coarse- (global) and fine-scale …

Thermovibrationally-driven flows and particle accumulation in microgravity environments
… flow and particle transport (Eulerian-Lagrangian one-way coupled approach). This work follows a logical approach with cases of increasing complexity being analysed as the discussion progresses, in particular, first the properties of this type of fluid flow are investigated in the single-phase …
