Cestodes of the order Onchoproteocephalidea II infecting cartilaginous fishes (Elasmobranchii) in South Africa
(North-West University (South Africa), 2022)South Africa is globally classified as the third most biodiverse country on Earth. However, the immense deficiency of taxonomic marine based initiatives, especially regarding parasitological research, within this region ... -
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 packed bed
(SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
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 and systems thermal-hydraulic analysis in the design and safety assessment of high-temperature reactors
(Woodhead Publishing, 2019)An overview is provided of the role of the various levels of CFD in the different stages of the design, analysis and evaluation of very-high-temperature reactor (VHTR) systems and molten salt reactor (MSR) systems. The ... -
CFD applications in the Pebble Bed Modular Reactor Project: a decade of progress
(Elsevier, 2011)Of all the systems and components that have to be designed for a nuclear plant, the Reactor Unit is the most significant since it is at the very heart of the plant. At Pebble Bed Modular Reactor (Pty) Ltd. (PBMR), the ... -
CFD modeling of particle charging and collection in electrostatic precipitators
(Elsevier, 2016)A CFD model was developed to describe the particle laden gas flow through an ESP, particle charging and collection. The corona discharge was modeled using the open source software OpenFOAM to solve the Poison and charge ... -
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
(North-West University, 2019)Fluidisation, which is a process governed by the suspension of particles in a closed area by blowing air or another medium through the bed of particles, is gaining popularity in industries like pharmaceuticals and mining, ... -
CFD simulation and experimental study of a hydrogen leak in a semi-closed space with the purpose of risk mitigation
(Elsevier, 2020)Computational fluid dynamics (CFD) methods were used to analyze hydrogen leakage in a semi-closed ventilation facility. The goal of the research was to apply numerical simulations to verify hydrogen distribution in the ... -
CFD simulation of an industrial wet flue gas desulfurization spray tower: a comprehensive model with special atttention devoted to the modeling of absorption and chemical reactions
(International Pittsburgh Coal Conference, 2016) -
CFD simulation of nuclear graphite oxidation
(North-West University, 2010)This study investigates the development of a strategy to simulate nuclear graphite oxidation with Computational Fluid Dynamics (CFD) to determine an estimate of graphite lost. The task was achieved by comparing the results ... -
CGE or SAM? Ensuring quality information for decision-making
(AJHTL, 2015)The purpose of this paper is to conduct an economic assessment of the Aardklop National Arts Festival (hereafter referred to as Aardklop) by means of applying both the SAM and CGE methods, in order to ensure quality ... -
Challenge and Opportunity: the ALI/III Global Principles Project
(2008)This article deals with an international project to establish the extent to which it is feasible to achieve a worldwide acceptance of the Principles of Cooperation among the NAFTA Countries together with the Guidelines ... -
