Modelling of losses in multi-stage axial compressors with subsonic conditions
(North-West University, 2003)
The need was identified to develop an analytical performance prediction code for subsonic multistage
axial compressors that can be included in network analysis software. It was found that
performance calculations based ...
A new integrated procedure for energy audits and analyses of buildings
(North-West University, 2003)
A rapid growth in the national electricity demand is placing an ever-increasing demand on the national electricity supply utility, Eskom. Projections show that the load demand in South Africa may exceed the installed ...
Steel slab surface quality prediction using neural networks
(North-West University, 2003)
Columbus Stainless grinds the majority of the steel slabs that are produced to improve the surface quality. However, the surface quality of some slabs is good enough not to be ground. If a reliable method can be found to ...
The design and implementation of information systems for ESCO energy savings software
(North-West University, 2003)
Electricity cost of buildings is a major expense for building owners. Improvements in the efficient utilisation of energy is therefore of concern to this economic sector. Unfortunately, existing energy audit tools are ...
Simulation and optimisation of gas storage tanks filled with capacitance
(North-West University, 2003)
The Pebble Bed Modular Reactor (PBMR) is a revolutionary small, compact and safe nuclear
power plant. It operates on a direct closed Brayton cycle. One of the unique features of this
concept is its load following capability ...
The numerical modelling of a flue gas precipitator
(North-West University, 2003)
Suspended fly-ash particles in industrial emission gasses have a major degrading effect on the whole environment. Electrostatic precipitation is one of the oldest and most effective gas-cleaning processes used today. ...
Thermo-fluid simulation of a rotating disc with radial cooling passages
(North-West University, 2003)
Turbine blade cooling via internal cooling channels is a very important aspect in
modern-day gas turbine cycles. The need for blade cooling stems from the fact
that higher cycle efficiencies requires higher maximum ...
Network simulation for the effective extraction of IP network statistics
(North-West University, 2003)
This study investigates the extent to which a communication sessions' QoS
parameters can be measured through only extracting TCP/IP header data. The effect
on these measurements based on the point of header extraction ...
Investigation, development and testing of a low cost Solar Heat Barrow (SHB) and purifier
(North-West University, 2003)
Many rural communities in South Africa do not have running water or electricity. The fetching and heating of water is therefore a time consuming and expensive daily ritual. The use of energy sources such as wood or coal ...
Assessment of the national DSM potential in mine underground services
(North-West University, 2003)
ESKOM is moving towards a price structure for electricity which reflects, as far as
possible, the real cost of generation. It is called real time pricing (RTP). ESKOM
developed this cost structure to coax customers to ...
