Performance of a solar air heater incorporating thermal storage
(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 ...
Performance trends of a large air-cooled steam condenser during windy conditions
(Stellenbosch : University of Stellenbosch, 2011-03)

A numerical investigation of the plenum chamber aerodynamic behaviour of mechanical draught air-cooled heat exchangers
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: The primary purpose of this dissertation is to further the understanding of the influence of
plenum chamber aerodynamic behaviour on mechanical draught air-cooled heat exchanger
(ACHE) performance. The ...
Prediction of the temperature distribution in asphalt pavement samples
(Stellenbosch : Stellenbosch University, 2005-04)
ENGLISH ABSTRACT: The convection heat transfer coefficient between an infinite, horizontal surface and the natural
environment is determined experimentally. It is shown that, during daytime, heat is
transferred due to ...
A finite volume method for the analysis of the thermo-flow field of a solar chimney collector
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: This study investigates the implementation of the finite volume numerical
method applicable to non-orthogonal control volumes and the application of
the method to calculate the thermo-flow field within ...
Inlet manifold tests and performance evaluation of dephlegmators in air-cooled steam condensers
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: Measurements on air-cooled reflux steam condensers or dephlegmators at different
power plants have shown that sections of these units do not transfer heat effectively
over a range of operating conditions. ...
Performance characteristics of packed bed thermal energy storage for solar thermal power plants
(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 ...
Effect of water maldistribution on cooling tower fill performance evaluation
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: A 1.5 x 1.5 m2 counter-flow fill performance test facility is described in detail.
Instrumentation was selected and installed in the cooling tower fill test facility and
calibrated to ensure measurement ...
Performance evaluation of natural draught cooling towers with anisotropic fills
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: In the design of a modern natural draught wet-cooling tower (NDWCT), structural
and performance characteristics must be considered. Air flow distortions and
resistances must be minimised to achieve ...
Flow through a solar chimney power plant collector-to-chimney transition section
(Stellenbosch : Stellenbosch University, 2004-12)
ENGLISH ABSTRACT: One of the areas of the fluid dynamic design of solar chimney power plants that has
not been investigated sufficiently is the collector-to-chimney transition section of a
single turbine layout. The ...
