Performance evaluation of a solar chimney power plant
(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 ...
A critical evaluation and refinement of the performance prediction of wet-cooling towers
(Stellenbosch : University of Stellenbosch, 2003-12)
The thermal performance prediction of wet-cooling towers is critically analyzed and refined. Natural draft
counterflow towers and mechanical draft counterflow and crossflow towers are considered. The Merkel,
Poppe and ...
Thermal charcteristics of a greenhouse for aquaculture
(Stellenbosch : University of Stellenbosch, 2006-03)
Successful housing and breeding of exotic animals or plants often requires an environment that is quite different to the ambient conditions present. The current study approached the problem of sub-optimal water temperatures ...
Evaluation and performance prediction of cooling tower rain zones
(Stellenbosch : University of Stellenbosch, 2007-03)
Cooling tower rain zone performance characteristics such as the loss coefficient
and the Merkel number are evaluated and simulated. To this end the influence of
drop diameter and drop deformation on the velocity, path ...
Steam flow distribution in air-cooled condenser for power plant application
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: Air-cooled steam condensers are used in arid regions where adequate cooling water is not available or very expensive. In this thesis the effect of steam-side and air-side effects on the condenser performance, ...
Performance trends of an air-cooled steam condenser under windy conditions
(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. ...
