Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles. (2021)
Thesis
ALAITA, D.A. 2021. Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1603672

Multi-phase flow is the type of flow common in the oil and gas industry, as oil reservoirs contain mixtures of oil, gas and water with sand particles from sandstone reservoirs. Accurate design of oil and gas production equipment greatly depends on de... Read More about Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles..

Computational fluid dynamics modelling of fluid flow inside fractured reservoirs. (2021)
Thesis
AL-MASHHADANIE, H.A.J. 2021. Computational fluid dynamics modelling of fluid flow inside fractured reservoirs. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1603660

Fractured media exist in most layers of the earth's crust, often dominating bulk properties of subsurface geological formations. Therefore, fractured media are involved in many key engineering sectors that impact humans living on Earth. Fractured for...

An investigation of casing structural integrity in shale gas horizontal wells during hydraulic fracturing using FEA and machine learning algorithms. (2021)
Thesis
MOHAMMED, A.I. 2021. An investigation of casing structural integrity in shale gas horizontal wells during hydraulic fracturing using FEA and machine learning algorithms. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1603216

Unconventional oil and gas operators are currently facing the challenge of casing lateral buckling and/or deformation during shale gas wells stimulation through hydraulic fracturing. Failure of the casing during this process can lead to huge financia...

A computational visual saliency model for images. (2021)
Thesis
NARAYANASWAMY, M. 2021. A computational visual saliency model for images. Robert Gordon University, MRes thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1447310

Human eyes receive an enormous amount of information from the visual world. It is highly difficult to simultaneously process this excessive information for the human brain. Hence the human visual system will selectively process the incoming informati... Read More about A computational visual saliency model for images..

Cooperative localisation in underwater robotic swarms for ocean bottom seismic imaging. (2021)

Spatial information must be collected alongside the data modality of interest in wide variety of sub-sea applications, such as deep sea exploration, environmental monitoring, geological and ecological research, and samples collection. Ocean-bottom se... Read More about Cooperative localisation in underwater robotic swarms for ocean bottom seismic imaging..

Numerical and experimental study of the impact of temperature on relative permeability in an oil and water system. (2021)
Thesis
BALOGUN, Y. 2021. Numerical and experimental study of the impact of temperature on relative permeability in an oil and water system. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1357866

Relative permeability is affected by several flow parameters, predominantly operating temperature and fluid viscosity. Fluid viscosity changes with temperature, which correspondingly affects the relative permeability. Temperature is believed to have...
