Carbon dioxide methanation in a catalytic microchannel reactor
(North-West University (South Africa) , Potchefstroom Campus, 2017)The work reported in this dissertation demonstrated the practicality of a catalytic microchannel reactor for CO2 methanation implemented via the Sabatier reaction for potential power-to-gas applications. A combined ... -
Catalytic hydrothermal liquefaction of industrial lignin to bio-oil
(North-West University (South Africa)., 2022)The negative implications of the world’s current fossil fuel systems are driving researchers to search for alternative energy resources. One of the alternative energy resources that has received attention is renewable fuels ... -
Catalytic microchannel reactor development for the removal of carbon monoxide from hydrogen-rich gas streams
(North-West University (South Africa), 2021)Currently, hydrogen (H₂) fuel cells are among the fastest emerging clean power generation technologies worldwide. The emergence of H₂ energy and fuel cells for power generation originates from the renewable energy sector, ... -
Catalytic steam gasification of large coal particles
(North-West University, 2011)Catalytic gasification has been studied extensively in order to develop more efficient and economic coal conversion processes. Fundamental studies regarding catalytic gasification have thus far focused on experimentation ... -
Cathodic protection system design framework for the petrochemical industry
(North-West University (South Africa) , Potchefstroom Campus, 2015)The aim is to establish a cathodic protection (CP) system design framework for the petrochemical industry in South Africa. The CP system design framework is destined to be used as a guideline when designing CP systems for ... -
A centralised data management system for the South African mining and industrial sectors
(North-West University, 2018)The digital universe is expanding at an exponential rate, and there is a greater variety of data. This phenomenon, known as big data, is making an impact in all industries - specifically in organisations. Organisations can ... -
Centralised vs decentralised PI control for an islanded multi-inverter microgrid
(North-West University (South Africa)., 2023)Energy supply security is arguably one of the most pressing challenges for both emerging and established countries around the world, as technology grows increasingly reliant on reliable energy. With the increase of ... -
CFD airfoil profile drag calculation using far-field wake analysis
(North-West University (South Africa), 2019)With the ever increasing cost of experimental data and the ultimate decrease of project lifespan from design to implementation it has become the aerodynamicist?s main priority to design and model new ideas with precise ... -
CFD analysis of the heat transfer from a self-launch sailplane radiator
(North-West University (South Africa), 2019)A self-launch sailplane is an aircraft equipped with a retractable engine/propeller combination which can take-off on its own power. The engine can also be used to extend flights if necessary. The engine-driven propeller ... -
CFD analysis of thermal dispersion in a structured pebble bed
(North-West University, 2019)Heat transfer mechanisms in packed beds are not entirely understood, which gave rise to thermal dispersion correlations that contain considerable amounts of empiricism. The empiricism resulted from incorporating a limited ... -
CFD modelling of air flow through a finned coil heat exchanger to improve heat transfer and pressure drop predictions
(North-West University (South Africa), 2020)In the current study, a method of lessening computational expense and model design effort is investigated for finned coil heat exchangers (FCHXs) by using STAR-CCM+ as simulation tool. The simulation model prediction ... -
CFD modelling of an ammonium nitrate fluidised bed: effect of distribution plate geometry
