  • Van Huyssteen, Salomon Stephanus (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: Modern-day processors are not getting any faster. Due to the power consumption limit of frequency scaling, parallel processing is increasingly being used to decrease computation time. In this thesis, ...
  • Steyn, Hermanus Johannes (Stellenbosch : University of Stellenbosch, 2009-12)
    ENGLISH ABSTRACT: In the primary circuit components of high temperature reactors, various unwanted particles have been found. These particles include, for example, graphite and silver- 110 (110mAg). The silver-110 (110mAg) ...
  • Kopke, Markus (Stellenbosch : University of Stellenbosch, 2008-03)
    This study investigates practical passive methods to improve the seakeeping of a Hydrofoil Supported Catamaran (Hysucat). The Hysucat is a hybrid vessel combining hydrofoil efficiency with the stability of catamarans. The ...
  • Ackers, Mogamat Sadley (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: The optimal design of a heat exchanger for a specified heat transfer, pressure drop and set of ambient conditions entails minimising space, weight, material usage and overall cost. However, the variables ...
  • Heyns, Johan Adam (Stellenbosch : Stellenbosch University, 2008-12)
    This study evaluates the performance characteristics of a power plant incorporating a steam turbine and a direct air-cooled dry/wet condenser operating at different ambient temperatures. The proposed cooling system uses ...
  • Allen, Kenneth Guy (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: Solar energy is by far the greatest energy resource available to generate power. One of the difficulties of using solar energy is that it is not available 24 hours per day - some form of storage is ...
  • Krige, David Schabort (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: Micro gas turbines used in the aerospace industry require high performance with a compact frontal area. These micro gas turbines are often considered unattractive and at times impractical due to their ...
  • Hedderwick, Richard Anthony (Stellenbosch : University of Stellenbosch, 2000-12)
    A solar chimney power plant consists of a central chimney that is surrounded by a transparent canopy located a few meters above ground level. The ground beneath this canopy or collector as it is known is heated by the ...
  • Gudmundsson, Yngvi (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: A wet-cooling tower fill performance evaluation model developed by Reuter is derived in Cartesian coordinates for a rectangular cooling tower and compared to cross- and counterflow Merkel, e-NTU and Poppe ...
  • De Wet, Andrew Louis (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: Stellenbosch University participated in a project to re-design the compressor section of a diesel locomotive turbocharger. Tests conducted on the prototype compressor showed possible rotating stall in ...
  • Brooks, Michael John (Stellenbosch : University of Stellenbosch, 2005-03)
    Parabolic trough solar collectors (PTSCs) constitute a proven source of thermal energy for industrial process heat and power generation, although their implementation has been strongly influenced by economics. In recent ...
  • Lombaard, Francois (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: In the present study, research was conducted to determine the feasibility of water energy storage through which the output of heated air by an upward facing solar air heater could be prolonged. Following ...
  • De Wet, Christiaan Louis (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The purpose of this investigation is to determine the performance of an axial ow compressor operating in a closed loop helium cycle under high through- ow conditions. The GTHTR300 four-stage helium ...
  • Louw, Francois G. (Stellenbosch : University of Stellenbosch, 2011-03)
    Please refer to full text to view abstract.
  • Van Rooyen, J. A. (Stellenbosch : University of Stellenbosch, 2007-03)
    Air-cooled steam condensers (ACSC’s) are increasingly employed to reject heat in modern power plants. Unfortunately these cooling systems become less effective under windy conditions and when ambient temperatures are high. ...
  • Donkin, Richard Philip (Stellenbosch : University of Stellenbosch, 2009-12)
    ENGLISH ABSTRACT: This project investigated the feasibility of incorporating photovoltaic cells into plastic roof tiles using injection moulding. Such tiles have the potential to provide robust and distributed electricity ...
  • Kooverji, Bavesh (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: A measurement device was developed to accurately determine the pneumatic power performance of an Oscillating Water Column (OWC) model in a wave flume. The analysis of the pneumatic power is significant ...
