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. ...
Analysis of evaporative coolers and condensers
(Stellenbosch : Stellenbosch University, 1988)
ENGLISH ABSTRACT: In this report various mathematical models for the thermal evaluation of evaporative coolers and condensers are presented. These models range from the exact model based on the work by Poppe [84P01] to ...
Modelling of dragline dynamics
(Stellenbosch : Stellenbosch University, 2000-03)
ENGLISH ABSTRACT: The utilisation ofDraglines to remove overburden in surface mining operations is often the process that determines the output of these operations. The bucket and its rigging have been identified as ...
A design programme for dilute phase pneumatic conveyors
(Stellenbosch : University of Stellenbosch, 1997-12)
A computer programme for the simulation of dilute phase pneumatic conveying of solids is presented. This includes positive pressure and vacuum pneumatic conveying. The characteristic conveying parameters such as the ...
A discrete vortex model for the calculation of aerodynamic loads on a blade of a N-bladed helicopter rotor in rectilinear flight
(Stellenbosch : Stellenbosch University, 1992)
ENGLISH ABSTRACT: A model for the calculation of aerodynamic loads on a blade of a n-bladed helicopter rotor in rectilinear flight was developed and computerized. The model is based on a lifting line blade representation ...
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 ...
