An aerodynamic CFD analysis of inlet swirl in a micro-gas turbine combustor

Author: Meyers, Bronwyn C ; Grobler, Jan-Hendrik ; Snedden, GC Date: Jul 2023 A combustor was designed for a 200N micro-gas turbine [1, 2] using the NREC preliminary combustor design method [1, 2, 3]. During the design process, there are various aspects where there are no definitive methodologies for specifying the ... Read more
A benchmark dataset for defect detection and classification in electroluminescence images of PV modules using semantic segmentation

Author: Pratt, Lawrence E ; Matheus, Jana ; Klein, R Date: Dec 2023 Electroluminescence (EL) images enable defect detection in solar photovoltaic (PV) modules that are otherwise invisible to the naked eye, much the same way an x-ray enables a doctor to detect cracks and fractures in bones. This paper presents ... Read more c b n d
The cost of production and storage of renewable hydrogen in South Africa and transport to Japan and EU up to 2050 under different scenarios

Author: Roos, Thomas H Date: Oct 2021 The decarbonisation of hard-to-abate sectors globally will require significant volumes of carbon-free hydrogen. An investigation has been performed to determine the cost at which hydrogen can be generated by electrolysis using renewable ... Read more
Defect detection and quantification in electroluminescence images of solar PV modules using U-net semantic segmentation

Author: Pratt, Lawrence E ; Govender, Devashen ; Klein, R Date: Nov 2021 Electroluminescence (EL) images enable defect detection in solar photovoltaic (PV) modules that are otherwise invisible to the naked eye, much the same way an x-ray enables a doctor to detect cracks and fractures in bones. The prevalence of ... Read more
Modelling photovoltaic power output using machine Learning techniques

Author: May, Siyasanga I ; Pratt, Lawrence E ; Roro, Kittessa T ; Bokoro, P Date: Aug 2022 This work focuses on modelling the power output of multiple PV technologies installed at the outdoor test facility of the Council for Scientific and Industrial Research (CSIR) in Pretoria. Extreme Gradient Boosting (XGB) and Artificial Neural ... Read more
Multi-resolution segmentation of solar photovoltaic systems using deep learning

Author: Kleebauer, M ; Marz, Christopher A ; Reudenbach, C ; Braun, M Date: Dec 2023 In the realm of solar photovoltaic system image segmentation, existing deep learning networks focus almost exclusively on single image sources both in terms of sensors used and image resolution. This often prevents the wide deployment of such ... Read more
PV module reliability scorecard - Round 1

Author: Pratt, Lawrence E ; Basappa Ayanna, Manjunath ; May, Siyasanga I ; Mkasi, Hlaluku W ; Maweza, Elijah L ; Roro, Kittessa T Date: Nov 2021 Solar PV system component reliability is key to longterm success for the PV industry, given the 25-year lifespan of PV generators. PV modules are one key component needed to deliver on the lifetime production of PV systems, as they are the ... Read more
Wind energy supply profiling and offshore potential in South Africa

Author: Karamanski, Stefan ; Erfort, G Date: Apr 2023 South Africa’s energy network is under severe pressure due to low supply and overwhelming demand. With an increase in renewable energy providers, specifically wind energy, knowing how the supply can satisfy the electricity demand may relieve ... Read more
