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..

Defect detection and condition assessment of adhesively-bonded joints using acoustic emission techniques. (2021)
Thesis
CRAWFORD, A.R. 2021. Defect detection and condition assessment of adhesively-bonded joints using acoustic emission techniques. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1603651

The aim of this study is to investigate the application of acoustic emission (AE) techniques to the defect detection and monitoring of adhesively-bonded joints. Pencil Lead Breaks (PLBs) have been used as a simulated AE source to experimentally inves...

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...

Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process. (2020)
Thesis
STAROST, K.J. 2020. Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

Polymer nanocomposites are becoming established widely across the industry due to (among other reasons) their lightweight performance advantages, and ability to meticulously target material properties with great control and precision. Despite the ben... Read More about Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process..

Petrophysical and geomechanical characterization of a marginal (Wabi) field reservoir in north-central Niger Delta. (2019)
Thesis
ZORASI, C.B. 2019. Petrophysical and geomechanical characterization of a marginal (Wabi) field reservoir in north-central Niger Delta. Robert Gordon University [online], MRes thesis. Available from: https://openair.rgu.ac.uk

The aim of this study is to evaluate marginal field petrophysical and geomechanical parameters, and to develop a model for analysis of geomechanical problems, in order to mitigate stress-related issues in drilling, development and reservoir managemen...

Structural and residual strength analysis of metal-to-metal adhesively bonded joints. (2019)
Thesis
PRATHURU, A. 2019. Structural and residual strength analysis of metal-to-metal adhesively bonded joints. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

The aim of this study is to propose a new simulation/experimental methodology to assess the residual strength of defective adhesive bonds. This incorporates defect detection in adhesive bonds and quantification of the effect of these defects on the a...
