Solid-fluid interactions in porous media : processes that form rocks
This thesis studies how rocks evolve due to the coupled effects of flow and chemical reaction. The study was motivated by various experimental observations, both in igneous and sedimentary rocks. In the first part of this thesis, growth of microscopic, pore-scale, features in sedimentary rocks is …

Modeling fluid interactions with the rigid mush in alloy solidification
… treatment of the interface between the bulk fluid and the rigid mushy zone. In this region, the non-linear and coupled behavior of heat transfer, fluid mechanics, solute transport, and alloy thermodynamics has a dramatic effect on macrosegregation predictions. This work investigates the …

Smoothing Particle Hydrodynamics parallel implementation for numerical modelling of solid-fluid interactions
… technique to analyse the behaviour of solids and fluids. The proposed solution makes use of different techniques to improve the computational complexity of the simulation. To improve the performance, a parallel solution of the SPH numerical solution is implemented on the GPU using the NVIDIA CUDA …

Computational Fluid Dynamic Study of Heaving-to
This study looks at the fluid interactions from the wake of a sail boat performing the heaving-to storm tactic in heavy weather seas with the waves. This interaction causes the wave height in the wake to be reduced. The fluid flow in the top layer of the wave is seen to move with the wake as the …

A study of chemical interactions between the Marcellus shale and attapulgite and bentonite clays
Chemical interactions occur between water based muds and shale formations. These shale-fluid interactions are often associated with problems that arise when drilling. This paper presents results from a study investigating chemical interactions that occurred between the Marcellus shale and …

Modeling and Simulation of Bubbles and Particles
… of several different diameters. Particle-fluid interactions observed through flow-visualization, particle concentration, particle-wall interactions, and Lagrangian statistics were all considered. These results were interpreted and compared to heavy-particle results where appropriate. …

A numerical framework for the direct simulation of solid-fluid systems
Our understanding of solid-fluid dynamics has been severely limited by the nonexistence of a high-fidelity modeling capability for these multiphase systems. Continuum modeling approaches overlook the microscale solid-fluid interactions from which macroscopic system properties emerge, while …

Thermodynamics of geologic fluids
Fluids play a vital role in essentially all geologic environments and processes, and are the principal media of heat and mass transfer in the Earth. The properties of geologic fluids can be diverse, as fluids occur at conditions ranging from ambient temperatures and pressures at Earth's surface, to …
