The influence of cross-winds on the performance of natural draft dry-cooling towers.
(Stellenbosch : University of Stellenbosch, 1992-12)
The effect of cross-winds on the performance of natural draft dry-cooling towers is studied by
means of isothermal model tests, a numerical simulation and full scale measurements. The
action of the wind on such towers ...
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 ...
Characteristics of gas-liquid counterflow in inclined ducts with particular reference to reflux condensers
(Stellenbosch : Stellenbosch University, 1997-12)
ENGLISH ABSTRACT: An experimental investigation on gas-liquid counterflow in inclined rectangular ducts is
conducted. The pressure drop across the sharp-edged gas inlet and the pressure gradient
inside the duct are ...
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 optimization of engineering systems with particular reference to dry-cooled power plants
(Stellenbosch : University of Stellenbosch, 1995-03)
Computer simulation programs were developed for the analysis of dry-cooling systems for power
plant applications. Both forced draft direct condensing air"cooled condensers and hyperbolic natural
draft indirect dry-cooling ...
Rotary regenerator design optimisation and heating surface selection
(Stellenbosch : Stellenbosch University, 1995)
ENGLISH ABSTRACT:
The rotary regenerator is far from a new device and since its invention more than 70 years ago it has developed into a carefully engineered product. They are mainly used for gas to gas heat transfer and ...
Steam flow distribution in air-cooled condensers
(Stellenbosch : Stellenbosch University, 1996-03)
ENGLISH ABSTRACT:
In this thesis the parameters affecting the steam flow distribution through an air-cooled
steam condenser, as found in power generating plants is investigated. The investigated
condenser configuration ...
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 ...
Pressure drop during reflux condensation of steam in an inclined elliptical tube
(Stellenbosch : Stellenbosch University, 1998-09)
ENGLISH ABSTRACT:
Zapke and Kroger developed a model for the pressure drop across flattened tubes
employed in reflux condensers. This model is based on adiabatic two-phase
countercurrent experiments and incorporates the ...
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 ...
