Adding up the numbers: COVID-19 in South Africa

Author: Suliman, Ridhwaan ; Mtsweni, Jabu S Date: Jun 2022 The SARS-CoV-2 pandemic has wreaked havoc globally, with over half a billion people infected and millions of lives lost. The pandemic has also interrupted every aspect of our lives, with most governments imposing various interventions and ... Read more
Development of a partitioned finite volume-finite element fluid-structure interaction scheme for strongly-coupled problems

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jul 2012 This work details the development of a computational tool that can accurately model strongly-coupled fluid-structure interaction (FSI) problems, with a particular focus on thin-walled structures undergoing large, non-linear deformations. The ... Read more
Development of strongly coupled FSI technology involving thin walled structures

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jan 2011 A strongly coupled finite volume-finite element fluid-structure interaction (FSI) scheme is developed. Both an edge-based finite volume and Galerkin finite element scheme are implemented and evaluated for modelling the mechanics of solids. ... Read more
An enhanced finite volume method to model 2D linear elastic structures

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Apr 2014 This paper details the evaluation and enhancement of the vertex-centred finite volume method for the purpose of modelling linear elastic structures undergoing bending. A matrix-free edge-based finite volume procedure is discussed and compared ... Read more
An enhanced matrix-free edge-based finite volume approach to model structures

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jan 2010 This paper presents the formulation, implementation and evaluation of an enhanced matrix free edge-based finite volume approach to model the mechanics of solids undergoing large non-linear deformations. The developed technology is evaluated ... Read more
A matrix free, partitioned solution of fluid-structure interaction problems using finite volume and finite element methods

Author: Suliman, Ridhwaan ; Oxtoby, Oliver F ; Malan, AG ; Kok, S Date: Jan 2015 A fully-coupled partitioned finite volume–finite volume and hybrid finite volume–finite element fluid-structure interaction scheme is presented. The fluid domain is modelled as a viscous incompressible isothermal region governed by the ... Read more
Modelling dynamic liquid-gas systems: Extensions to the volume-of-fluid solver

Author: Heyns, Johan A ; Oxtoby, Oliver F ; Suliman, Ridhwaan Date: Jun 2013 This study presents the extension of the volume-of-fluid solver, interFoam, for improved accuracy and efficiency when modelling dynamic liquid-gas systems. Examples of these include the transportation of liquids, such as in the case of fuel ... Read more
The stability and dynamic behaviour of fluid-loaded structures

Author: Suliman, Ridhwaan ; Peake, N Date: Jul 2015 The deformation of slender elastic structures due to the bulk motion of fluid around it is a common multiphysics problem encountered in many applications. In this work we implement two computational FSI approaches in a partitioned manner: a ... Read more
