Author:Jones, Bevan W S; Malan, Arnaud G; van Rooyen, Jacobus ADate:2015Presented in this paper is an accuracy enhancing r-refinement scheme based on the ballvertex method [1, 2]. Due the success of the method in mesh movement, this work seeks to extend its use to error minimization for computational fluid dynamics ...Read more
Author:Van Rooyen, Jacobus ADate:2017Axial air flow fans are widely used for air movement. In an increasingly international and competitive market, smaller fan companies find themselves in need of rapid preliminary design. This need is addressed in this study through the development ...Read more
Author:Malan, LeonDate:2018Direct Numerical Simulation of two-phase ow is used extensively for engineering research and fundamental fluid physics studies. This study is based on the Volume-Of-Fluid (VOF) method, originally created by Hirt and Nicols. This method has ...Read more
Author:Merrick, Dane GlenDate:2015This project is concerned with advection discretization technology within the field of Computational Fluid Dynamics (CFD). To this end, two novel methods are proposed which are dubbed the Enhanced Taylor (ET) Schemes. The model equation for ...Read more
Author:Fillis, Vernon WDate:2018The Fukushima Daiichi Nuclear Power Plant accident created renewed international interest in the behaviour of spent fuel subsequent to a complete loss of water inventory in a spent fuel pool (SFP). The study conducted in this dissertation ...Read more
Author:Jones, Bevan W SDate:2015This project investigates the use of a truss network, a structural mechanics model, as a metaphor for adapting a computational fluid dynamics (CFD) mesh. The objective of such adaptation is to increase computational effi- ciency by reducing ...Read more
Author:Eferemo, DanielDate:2017The principal objective of this study is to investigate, develop and verify a framework for determining the convective heat transfer co-efficient from a cylindrical model that can easily be adaptable to more complex geometry - more specifically ...Read more
Author:Nchupang, Mojalefa PrinceDate:2020Numerical simulations of incompressible flows are unequivocally important due to their numerous industrial applications. These applications ranges from the large-scale fluid's flow modelling such as aerodynamics [1], atmospheric-ocean modelling ...Read more
Author:Farao, JavonDate:2015The purpose of this study was to initiate the development of a full aircraft model (FAM) for the purpose of non-linear loads calculation of an aircraft. The FAM is employed during the design process of an aircraft and comprises of various ...Read more
Author:Changfoot, Donovan MDate:2017This dissertation outlines the development of a parallel 3D hybrid finite-volume- finite-difference solver. As motivation for such a scheme, the specific application area under consideration is modeling the trailing vortices shed from the ...Read more
