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...

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...

Uncertainty reduction in reservoir parameters prediction from multiscale data using machine learning in deep offshore reservoirs. (2020)
Thesis
ARIGBE, O.D. 2020. Uncertainty reduction in reservoir parameters prediction from multiscale data using machine learning in deep offshore reservoirs. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

Developing a complete characterization of reservoir properties involved in subsurface multiphase flow is a very challenging task. In most cases, these properties - such as porosity, water saturation, permeability (and their variants), pressure, wetta...

CFD modelling of flow-induced vibration under multiphase flow regimes. (2020)
Thesis
ASIEGBU, N.M. 2020. CFD modelling of flow-induced vibration under multiphase flow regimes. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

Internal multiphase flow-induced vibration (MFIV) in pipe bends poses serious problems in oil and gas, nuclear and chemical flow systems. The problems include: high amplitude displacement of the pipe structure due to resonance; fatigue failure due to...

CFD modelling of pipe erosion under multiphase flow regimes. (2020)
Thesis
OGUNSESAN, O.A. 2020. CFD modelling of pipe erosion under multiphase flow regimes. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

Pipe erosion due to sand transport can have an adverse effect on the production efficiency of pipe-lines and other related flow systems. Proper knowledge of the flow characteristics, particle behaviour and geometric effects is very important in the a... Read More about CFD modelling of pipe erosion under multiphase flow regimes..

Optimization of indentification of particle impacts using acoustic emission. (2018)
Thesis
HEDAYETULLAH, A.M. 2018. Optimization of indentification of particle impacts using acoustic emission. Robert Gordon University, PhD thesis.

Air-borne or liquid-laden solid particle transport is a common phenomenon in various industrial applications. Solid particles transported at severe operating conditions such as high-flow velocity can cause concerns for structural integrity, through w...
