Assessment of the national DSM potential in mine underground services
(North-West University, 2003)ESKOM is moving towards a price structure for electricity which reflects, as far as possible, the real cost of generation. It is called real time pricing (RTP). ESKOM developed this cost structure to coax customers to ... -
Design and optimisation of a solar thermal powered Aqua-Ammonia diffusion-absorption heat pump cycle under seasonal variance for residential use
(North-West University (South Africa)., 2021)The diffusion-absorption refrigerator was patented by Von Platen and Munters (1926). The conventionally low coefficient of performance and the high driving temperature have been the focus of most research since its ... -
Design optimisation and experimental evaluation of a grain vibration screen
(2016)Mechanical screening is an important process which is used in a wide range of industries. This study focused on screens in the agricultural industry used for cleaning and classifying of grain. Mathematical models were ... -
Developing a digital twin for addressing complex mine ventilation problems
(North-West University (South Africa), 2021)The ventilation system of a deep-level mine is complex and dynamic, which makes it challenging to identify changes in such a system and even more so to predict the effect of these changes with conventional approaches. An ... -
Development of a lean optimisation plan for a wire manufacturing process
(North-West University (South Africa), 2019)The growing demand for maximum operational efficiency has driven organisations towards implementing lean manufacturing as a management philosophy. However, a gap still exists between the available information on lean ... -
An energy efficient mass transportation model for Gauteng
(North-West University, 2011)Public transportation in South Africa is characterized by little or no consideration for energy efficiency and use of cleaner fuels. In the case of transport planning in South African cities, no assessment of the economic ... -
Evaluation of sub- and supercritical Rankine cycle optimisation criteria
(North-West University (South Africa) , Potchefstroom Campus, 2017)The main purpose for this study has been to model an advanced real Rankine cycle for sub and super-critical boilers with all the components as encountered in the industry mathematically and to optimise each cycle. First ... -
Evaluation of upstream and downstream process parameters on electrostatic precipitator performance
(2013)New emission legislation regarding air pollution control, as instructed by the Department of Environmental Affairs (DEA) to Eskom Generation Power Stations, implies a particulate emission limit of 100 mg/Nm3 for all existing ... -
Exact approaches towards solving generator maintenance scheduling problems
(North-West University (South Africa), 2019)The holistic management of a national power system is faced with multiple long and short-term scheduling challenges. One of the key long-term scheduling problems is referred to as the generator maintenance scheduling problem ... -
Improving energy cost performance of steel production mills
(North-West University, 2018)The global steel supply capacity is more than the demand. This has caused an increase in competition and imports to some countries. South Africa is one of the affected countries and the effects have been seen in the closing ...
