Numerical Simulation Of The Atmospheric Boundary Layer Over Complex Topography: A Modern Approach To A Classical Problem
… that the results from LES are more accurate than mesoscale simulations. Lastly, it was found that the errors in the present simulation are a result of the roughness model used over the sea surface.

Finite element method with hierarchical domain decomposition : enabling experimentally relevant mesoscale models
Mesoscale materials such as metallic glass present a difficult modeling challenge because their time and length scales place them in a gap where neither continuum mechanics nor quantum mechanics-based models are computationally tractable. The STZ dynamics model is a mesoscale approach to modeling …

Simulating Nanoparticle and Polymer Dynamics in Solution
… hydrodynamic interactions in coarse-grained, mesoscale simulations. We apply MPCD to study transport in nanoparticle-polymer systems and the effects of many-body hydrodynamic interactions on this behaviour. We demonstrate that the translational center-of-mass motions of both nanoparticles and …

Exploring the link between microstructure statistics and transverse ply fracture in carbon/epoxy composites
… the real microstructure. We then perform some mesoscale simulations that focus on the cohesive failure of the interfaces between the fibers and the surrounding matrix material. Finally, an analytical material sensitivity formulation is derived and implemented using the direct differentiation …

Gap winds in a fjord : Howe Sound, British Columbia
… by statistical evaluation compared to other mesoscale simulations, and by visual inspection of the fields. The RAMS output, which has very high temporal and spatial resolution, provided much additional information about the details of gap flow. In particular, RAMS results suggested a close …

Stress Effects on Phase Morphological and Compositional Non-uniformity in Intercalation Compounds
… In this thesis, theoretical analyses and mesoscale simulations are carried out to elucidate and predict how coherency stress, which usually arises due to the solute concentration dependence of lattice parameter, impacts the evolution of phase morphology and solute composition distribution …

Molecular simulation method development and implementation for fuel cell catalyst layers
… in the catalyst layer. To this end, we employ mesoscale dissipative particle dynamics (DPD), a well-established coarse-grained molecular dynamics method, to model such thin film confined from both sides. Our results summarised in Chapter 2 reveal a confinement-induced water clustering as well …

Effect of concrete heterogeneity on FRP-to-concrete bond behaviour
… FRP-to-concrete bonded joint with the focus on mesoscale mechanical behaviour of concrete and the effect of concrete heterogeneity. <br/>A 2D mesoscale modelling framework is proposed, integrating the capabilities of generating mesoscale geometric structures with Matlab programming, …

Molecular Dynamics Studies of Grain Boundary Mobilities in Metallic and Oxide Fuels
… drag effects, but also can be used as inputs for mesoscale simulations to examine polycrystalline grain growth with anisotropic GB mobility and in turn examine how the fuel performance parameters change with these properties.
