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 ...
Losses in the inlet section of counterflow wet-cooling towers
(Stellenbosch : Stellenbosch University, 1998-12)
ENGLISH ABSTRACT: The flow resistances in the inlet sections of counterflow wet-cooling towers are investigated and
correlations are derived for inclusion in a one-dimensional tower performance model.
The rain zone loss ...
Evaluation of natural draught wet-cooling tower performance uncertainties
(Stellenbosch : Stellenbosch University, 2007-03)
ENGLISH ABSTRACT: A natural draught wet-cooling tower (NDWCT) was modelled using the Merkel method with an
improved energy equation as recommended by Kloppers and Kroger (2005a) - referred to as the
Improved Merkel ...
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 ...
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 ...
Die invloed van versteurde inlaatvloeipatrone op aksiaalwaaiers
(Stellenbosch : Stellenbosch University, 1990-12)
ENGLISH ABSTRACT: The causes of disturbances in the flow patterns at the
inlets of axial flow fans that are used in mechanical draft
cooling towers and the effects of these disturbances on the
fans, were investigated.
A ...
Performance characteristics of hybrid cooling towers
(Stellenbosch : Stellenbosch University, 1995-09)
ENGLISH ABSTRACT:
Different wet/dry and dry/wet cooling tower configurations are investigated and the
advantages and disadvantages of separate and combined (hybrid) configurations are discussed.
Some existing hybrid ...
The influence of temperature stratification in the lower atmospheric boundary layer on the operating point of a natural draft dry-cooling tower
(Stellenbosch : Stellenbosch University, 1997-11)
ENGLISH ABSTRACT:
Natural draft dry-cooling towers for power stations are designed to reject heat at a
prescribed rate under specified atmospheric conditions. In the past, cooling tower
designs were based on the annual ...
