LARGE-EDDY SIMULATION OF DEEP-WATER HYDROCARBON PLUME DYNAMICS
… hydrocarbon plume is strongly affected by the gas dissolution and hydration process that weakens the bubble-induced buoyancy for driving the plume. In this study, a new modeling strategy is developed to efficiently incorporate the gas dissolution and hydration effects into a fast …

In-line measurement of solibility of physical blowing agents in thermoplastic melts as related to extrusion foaming
… solubility data by observing the onset of gas bubble formation/dissolution. This method offers a number of advantages over the existing conventional methods. It can be easily used to obtain solubility data for many foamable thermoplastic-physical blowing agent systems at high pressure and …

Hydrogen Gas Production and Effects During Remediation Using Nano-scale Zero-valent Iron
… of the potential effects of hydrogen gas (H2) exsolution during nanoscale zero-valent iron (nZVI) groundwater remediation applications. An improved understanding of gas exsolution and its effects can be applied to remediation technologies that produce gas in excess of solubility …

Multiphase flow in porous media with phase transitions : from CO₂ sequestration to gas hydrate systems
… global carbon budget and the fate of greenhouse gases (GHG). Among engineered systems, one promising tool to reduce atmospheric emissions of anthropogenic carbon dioxide (CO₂) is geologic sequestration of CO₂ , which entails the injection of CO₂ into deep geologic formations, like saline …

Development and characterisation of air-liquid interface exposure systems for cell and tissue cultures
… consideration of particle deposition and gas dissolution within the complex structure of the respiratory system. Until the last decade or so, methodology relied heavily on animal models or limited, submerged cell culture models that did not capture air-liquid interactions, identifying the …

Performance Evaluation of an Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
… impact. The reaction frequency factor (RFF) for gas exsolution from bubble to gas phase almost shows no influence on the simulated oil recovery. In comparison, the RFFs for gas dissolution and exsolution from oil phase to bubble affect the oil recovery to a larger extent. The injection pressure …

Deformation and fracture of PMMA with application to nanofoaming and adhesive joints
This thesis contributes to the understanding of the deformation and fracture of methyl methacrylate (MMA)-based polymers in the context of void growth. The first part of the thesis focuses on the prediction of void growth during solid state nanofoaming of polymethyl methacrylate (PMMA). These …
