Delevitation modelling of an active magnetic bearing supported rotor
(2014)The problem addressed in this thesis is the delevitation modelling of an active magnetic bearing (AMB) supported rotor. A system model needs to be developed that models the highly non-linear interaction of the rotor with ... -
Development of a hydrocyclone separation efficiency model using artificial neural networks
(North-West University (South Africa) , Potchefstroom Campus, 2016)A hydrocyclone is an apparatus that is widely used throughout the mineral processing industry. Usually the hydrocyclone is used for the classification, desliming or dewatering of slurries. It is inexpensive, application-efficient ... -
The effect of feed water TDS on RO membrane rejection rates and performance
(North-West University (South Africa)., 2023)Power generation is a major user of fresh water, which is becoming important for Eskom and South Africa due to the water-scarce status. Therefore, the water usage at a thermal power station is a key metric and reverse ... -
Fermentation coupled with pervaporation : a kinetic study
(North-West University, 2011)Ethanol production through biomass fermentation is one of the major technologies available to produce liquid fuel from renewable energy sources. A major problem associated with the production of ethanol through fermentation ... -
Fluidised bed gasification of high-ash South African coals : an experimental and modelling study
(2014)South Africa has large coal reserves and produces approximately 74% of its primary energy from coal. Coal gasification using moving bed gasifiers is one of the most important coal utilisation technologies, consuming ± ... -
Heat and mass transfer model for a coffee roasting process
(North-West University (South Africa) , Potchefstroom Campus, 2017)The roasting of coffee is a complex process and it takes years of experience to be able to produce a quality cup of coffee (as well as consistently reproducing the same quality coffee). Although there are various factors ... -
Model for microwave absorption and heat transfer in a combination washer dryer
(North-West University, 2013)The work presented within this dissertation focusses on the development of affinite element method (FEM) model for the microwave absorption and heat transfer within a microwave combination washer dryer (MCWD). FEM will be ... -
Modelling of electricity cost risks and opportunities in the gold mining industry
(2014)Carbon tax, increased reactive power charges, tariff increases and the Energy Conservation Scheme (ECS) are some of the worrying electricity cost risks faced by large South African industries. Some of these proposed cost ... -
Modelling of losses in multi-stage axial compressors with subsonic conditions
(North-West University, 2003)The need was identified to develop an analytical performance prediction code for subsonic multistage axial compressors that can be included in network analysis software. It was found that performance calculations based ...
