(2017)Abstract available in PDF file. -
Numerical and experimental investigations of optimal fatty acid methyl ester hybrid for enhanced engine performance and emission mitigation in the conventional compression ignition strategy.
(2020)The utilization of petroleum-based diesel fuel to power compression ignition (CI) engines has been hampered by inefficient combustion process resulting in unsatisfactory engine performance and emission of hazardous gases. ... -
Numerical simulation of the structural response of a composite rocket nozzle during the ignition transient.
(2009)The following dissertation describes an investigation of the structural response behaviour of a composite solid rocket motor nozzle subjected to thermal and pressure loading during the motor ignition period, derived on ... -
An on-demand fixture manufacturing cell for mass customisation production systems.
(2017)Increased demand for customised products has given rise to the research of mass customisation production systems. Customised products exhibit geometric differences that render the use of standard fixtures impractical. ... -
Open architecture control system for a modular reconfigurable machine tool.
(2013)The present day manufacturing environment has forced manufacturing systems to be flexible and adaptable to be able to match the product demands and frequent introduction of new products and technologies. This research ... -
The optimal design of laminated plates for maximum buckling load using finite element and analytical methods.
(1994)In the first part of the study, finite element solutions are presented for the optimal design of symmetrically laminated rectangular plates subject to a combination of simply supported, clamped and free boundary conditions. ... -
Optimisation and design of two micro-hydro turbines for medium and low head applications.
(2000)The necessity to develop an automated process for the design of micro-hydro power systems was based on the increasing demand for hydropower as a renewable energy source and to develop cost effective power supplies to ... -
Optimisation of the process parameters of the resin film infusion process.
(1999)The resin film infusion process or RFI is a vacuum assisted moulding method for producing high quality fibre reinforced components. The goals of this research have been to investigate this new process, with the aim of ... -
The optimisation of train make-up and train handling-simulating longitudinal train dynamics.
(2000)The South African rail industry is undergoing a phase of restructuring and much focus is concentrated on re-engineering i.e. optimising the utilisation of available assets and using existing technology in order to improve ... -
Optimisation of welding parameters to mitigate the effect of residual stress on the fatigue life of nozzle–shell welded joints in cylindrical pressure vessels.
(2017)The process of welding steel structures inadvertently causes residual stress as a result of thermal cycles that the material is subjected to. These welding-induced residual stresses have been shown to be responsible for ... -
Optimization of turbine design for deep sea (ocean current) power energy technology.
(2016)The main objective of this thesis is to study renewable energy based on ocean current energy conversion. Different technologies based on ocean energy conversion are described and this research focuses on the design of a ... -
