CFD investigation of the atmospheric boundary layer under different thermal stability conditions

Pieterse, Jacobus Erasmus (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: An accurate description of the atmospheric boundary layer (ABL) is a prerequisite for computational fluid dynamic (CFD) wind studies. This includes taking into account the thermal stability of the ...
The CFD simulation of an axial flow fan

Le Roux, Frederick Nicolaas (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: The purpose of this project is to investigate the method and accuracy of simulating axial ow fans with three-dimensional axisymmetric CFD models. Two models are evaluated and compared with experimental ...
Characterisation of a solar roof tile (SunSlates™) : with focus on local applicability and conditions

Rautenbach, Karel Frederick (Stellenbosch : Stellenbosch University, 2008-12)

Three SunSlates™ were investigated to predict the performance of a fully installed system. The three slates were mounted on a fixed tilt of 30°, but with different orientations. The tilt is close to latitude of the ...
Comparative evaluation of a hydrofoil-assisted trimaran

Moolman, Ryno (Stellenbosch : University of Stellenbosch, 2005-12)

This work is concerned with the design and hydrodynamic aspects of a hydrofoil-assisted trimaran. A design and configuration of a trimaran is evaluated and the performance of a hydrofoil-assisted trimaran is effectively ...
A comparative evaluation of non-linear time series analysis and singular spectrum analysis for the modelling of air pollution

Diab, Anthony Francis (Stellenbosch : Stellenbosch University, 2000-12)

ENGLISH ABSTRACT: Air pollution is a major concern III the Cape Metropole. A major contributor to the air pollution problem is road transport. For this reason, a national vehicle emissions study is in progress with the ...
A comparative study on the performance of biodiesel in a modern 1.9L turbo diesel engine

Kotze, Johan (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: This thesis comprises of the testing and evaluation of a modern diesel engine running on both biodiesel and mineral diesel on the upgraded Bio-fuels Testing Facility (BTF) at Stellenbosch University. The ...
Computational and experimental investigation of chamber design and combustion process interaction in a spark ignition engine

Van der Westhuizen, H. J. (Stellenbosch : Stellenbosch University, 2003-12)

ENGLISH ABSTRACT: The automotive industry in South Africa is expanding as a result of pressure on the world economy that forces vehicle manufacturers to outsouree work to developing countries. In order to add value to ...
A computational fluid dynamic analysis of the airflow over the keystone plant species, Azorella selago, on sub-antarctic Marion Island

Combrinck, Madeleine Lelon (Stellenbosch : University of Stellenbosch, 2009-03)

Research conducted on Marion Island aims at predicting the consequence of climate change in the Subantarctic region, as well as for other terrestrial ecosystems. The island has the ideal ecosystem, due to its size, ...
A computational fluid dynamics study of the near surface wind patterns over a desert dune and the effect on seed dispersion

Joubert, Eugene Christiaan (Stellenbosch : Stellenbosch University, 2010-03)

ENGLISH ABSTRACT: This project originated when a team of scientists at the Gobabeb training and research and centre observed seed accumulation sites on the slope of sand dunes in the Namib Desert. Seeds that accumulate ...
Conceptual design of a fixture-based reconfigurable spot welding system

Sequeira, Michael Allan (Stellenbosch : University of Stellenbosch, 2009-03)

This thesis details the conceptual design of a fixture-based, reconfigurable, automated spot welding system aimed at manufacturing various sub-assemblies of circuit breakers. The welding operations are currently done using ...
Conceptual design of a fixtureless reconfigurable automated assembly system

Dymond, F. S. D. (Stellenbosch : University of Stellenbosch, 2009-12)

ENGLISH ABSTRACT: The conceptual design of a fixtureless reconfigurable automated spot welding system for manufacturing subassemblies for residential circuit breakers was investigated. This research was aimed at developing ...
