Design analysis methods for Stirling engines
(Energy Research Centre, University of Cape Town, 2008)Worldwide attempts are being made to increase the use of our renewable energy sources as well as to use our current fossil fuel energy sources more efficiently. Waste heat recovery forms a substantial part of the latter ... -
A heat pipe heat recovery heat exchanger for a mini-drier
(Energy Research Centre, University of Cape Town, 2006)This paper considers the thermal design and the experimental testing of a heat pipe (thermosyphon) heat exchanger for a relatively small commercially available mini-drier. The purpose of the heat exchanger is to recover ... -
Stainless steel finned tube heat exchanger design for waste heat recovery
(Energy Research Centre, University of Cape Town, 2006)Around the world the implementation of heat recovery systems play an increasingly important role in the engineering industry. Recovered energy is utilised in production plants (especially in the food industry) and saves ... -
Performance of a parabolic trough solar collector
(Energy Research Centre, University of Cape Town, 2006)The performance of a South African parabolic trough solar collector (PTSC) module has been characterised using the ASHRAE 93-1986 standard. The collector is designed for component testing and development in a solar ... -
Utilization of basic multi-layer perceptron artificial neural networks to resolve turbulent fine structure chemical kinetics applied to a CFD model of a methane/air piloted jet flame
(Yildiz Technical University, 2018)ENGLISH ABSTRACT: This work investigates and proposes an alternative chemistry integration approach to be used with the eddy dissipation concept (EDC) advanced combustion model. The approach uses basic multi-layer perceptron ... -
The improvement of a battery thermal management system for an electric vehicle
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: The increasing cost of fossil fuels, along with the growing concern over climate change, has sparked renewed interest in the research and development of Electric Vehicles (EVs). This thesis focusses on ... -
Design of a soft pheumatic oscillator
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: The field of soft robotics and more specifically flexible fluidic actuators makes use of conventional control systems that are usually tethered and cumbersome. This project followed a systems engineering ... -
Design and development of a morphing wing utilising flexible materials
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Aircraft wings are required to operate in a multitude of different aerodynamic conditions. To compensate for these varying conditions, modern aircraft are equipped with devices that can alter the ... -
Operational modal analysis on the SA Agulhas II
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Full-scale operational measurements were conducted on a polar vessel during an expedition to Antarctica. Accelerometers distributed along the length of the vessel were used to capture vertical, lateral ... -
Development of a canine knee implant
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Patient-specific canine knee implants have the potential to restore lost mobility to knees experiencing joint degradation. Due to high costs associated with current implant solutions, this research focused ... -
Numerical investigation of heat transfer enhancement in solar receiver tubes
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Concentrated solar power (CSP) could serve as a viable means of meeting the demands of an increasing rise in electricity requirements, as well as, being a means to produce clean and renewable energy. ... -
The effect of hub configuration on the performance of an air-cooled steam condenser fan
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Axial flow fans used in air-cooled condensers are typically analysed with smooth rounded hubs due to their superior performance. However, such a hub increases the manufacturing and installation costs ... -
Design and validation of a hip and quadriceps assembly mechanism for a knee squat simulator
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Given the prevalence of osteoarthritis, knee implants are continuously being improved. In vitro experiments can be used to evaluate the performance of an implant by investigating biomechanical behaviour ... -
Measurement of in vivo patella and achilles tendon forces during treadmill running
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Tendons are the connections that translate forces from muscles to bone and are essential to the musculoskeletal system movement during locomotion. The load experienced during running is believed to be a ... -
Direct measurement of patellofemoral contact force
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: Osteoarthritis is a prevalent disease that affects millions of people around the world. The most effective treatment is a total knee arthroplasty. However, post-operative patellofemoral problems do arise, ... -
Mapping the relationship between the subjective response of jurors to fan blade parameters
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: The noise generated by computer cooling fans is known to be a factor which may cause discomfort in the workplace. Aerodynamic noise caused by fan blades has been identified to be a significant factor ... -
Design methodology for an inflatable membrane aerofoil using numerical shape optimisation
(Stellenbosch : Stellenbosch University., 2020-04)ENGLISH ABSTRACT: The use of inflatable wings for unmanned aerial vehicles over their fixed-winged counterparts has many advantages such as the wing’s ability to be folded up when deflated, this saves storage space. ... -
Development of a micro-gas turbine for central receiver concentrating solar power systems
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: There is limited access to electricity in much of Southern Africa, yet this region receives some of the highest solar irradiation worldwide. Consequently, there is a huge potential for the deployment ... -
An architecture for the digital twin of a manufacturing cell
(Stellenbosch : Stellenbosch University., 2020-03)ENGLISH ABSTRACT: The ongoing development of modern manufacturing technology contributes to the rise of the fourth industrial revolution, or Industry 4.0. The digital twin is considered to be key for interaction between ... -
Unsteady analysis of a generic non-axisymmetric hub endwall contour as applied to a rotating turbine at on and off- design conditions
(SAIMechE, 2018)Numerous researchers have investigated various techniques to reduce loss in gas turbine engines. One such technique that has shown promise is endwall secondary flow control using non-axisymmetric endwall contouring. Previous ...
