Development of a universal impeller test rig for scaled testing of high performance impellers.
(2014)This dissertation presents the validation of a universal impeller test rig, designed by the author and constructed at the University of KwaZulu-Natal (UKZN). The research was conducted as part of UKZN’s Aerospace Systems ... -
Development of the smart aircraft bolt.
(2002)The work contained herein is in pursuance of the Development of the SMART aircraft bolt. Failure of the bolt in the aircraft wing is taken for granted in the project, and the consequent repairs are presently very costly. ... -
Development of thermal energy storage and cooker module for the integrated solar energy project.
(2008)Large percentages of the South African population have no access to grid power and are located at distances that make provision for such facility uneconomical. Also traditional fuels are under pressure. Most areas in ... -
Double shrouded horizontal axis wind turbine.
(2013)This research study deals with the design and optimization of a Shrouded Horizontal Axis Wind Turbine which is an emerging system in the field of renewable energy resources. The literature review shows that several authors ... -
Drying of faecal sludge from ventilated-improved pit latrines( VIP latrines) using solar thermal energy.
(2019)Ventilated improved pit (VIP) latrines are a basic form of sanitation in South Africa. The main challenge facing the application of VIP latrines is the gradual fill up of the pit due to usage. A sustainable way of treating ... -
Economic evaluation of a district cooling system incorporating thermal storage.
(2003)The following report investigates district cooling systems. This form of technology provides an alternative means of providing cooling. In a traditional cooling system each building would include cooling ... -
Effect of displacement feedback control on the frequencies of cantilevered beams with tip mass and axial load using piezo actuators.
(2014)This work provides a study of the natural frequencies of a cantilevered beam with tip mass and axial load. Displacement feedback control is applied using piezo actuators attached to the top and bottom of the beam. The ... -
The effect of fretting marks introduced during strand winding on the fatigue performance of transmission line conductors.
In this research, the Elasto-plastic interlayer contact of the TERN ACSR conductor used on Eskom’s 400kV transmission lines is investigated. Characterization of the elliptical contact marks using eucentric tilting in SEM ... -
The effects of exhaust gas recirculation (EGR) on the performance of diesel engine.
(2018)The aim of this work was to study the effects of EGR on the performance of a diesel engine using waste plastic pyrolysis oil (WPPO) and conventional diesel (CD). WPPO was developed through the pyrolysis extraction method. ... -
Energy efficiency in motor vehicle assembly plant : a case study of a vehicle assembly plant in Kenya.
(2014)Energy is defined as the capacity to do work and comes in various forms such as motion, heat, light, electrical, chemical, nuclear, and gravitational. There are two forms of energy: primary energy which is extracted or ... -
Energy efficiency in the South African cement finishing plant: drivers, barriers and improvement.
(2017)The cement production is an energy demanding industry that requires a high degree of attention regarding energy use in South Africa. Within the last decade, South Africa has faced a shortage of electricity supply, because ... -
