Deriving nearshore wave climate along South African coast

Author: Rossouw, M ; Rautenbach, C ; Page, Philip R ; Harribhai, Jatin Date: Apr 2015 The present study addressed aspects of the highly interrelated study area of coastal safety and vulnerability, climate change and setback lines for South African coast. A medium resolution numerical wave analysis was undertaken, in the form ... 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
On equivalent radius of curvature for PWL geometrical modeling a loop antenna

Author: Lysko, Albert A Date: Nov 2012 A circular loop antenna is often numerically modeled using a regular polygon. This approach is simple and robust, yet it alters the circumference of the loop and may thus shift the resonance frequency in the numerical model. This letter ... Read more
Particle image velocimetry measurements and numerical modeling of a saline density current

Author: Gerber, G ; Diedericks, G ; Basson, GR Date: Mar 2011 Particle image velocimetry scalar measurements were carried out on the body of a stably stratified density current with an inlet Reynolds number of 2,300 and bulk Richardson number of 0.1. These measurements allowed the mass and momentum ... Read more
The ribbon microphone - an educational aid: use of a ribbon microphone to teach multi-discipline computer simulation skills

Author: Van Wyk, Marius ; Meyer, P Date: Jul 2016 The ribbon microphone serves as an excellent aid to learn computer simulation and computational skills. Simulation of this seemingly simple device is all but trivial. The ribbon microphone is an all-in-one example for simulations in acoustics, ... 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
