Improved mine cooling system performance through the control of auxiliary systems
(North-West University, 2012)
Industrial and mining sectors are amongst the largest single energy consumers in South
Africa, making them a primary focus for implementing energy saving initiatives.
Refrigeration systems on mines are responsible for ...
The development of a methodology to measure & verify the impact of a national solar water heating program
(North-West University, 2010)
The School for Mechanical Engineering at the North-West University is home to one of South Africa's most established Measurement & Verification (M&V) teams. The team is involved with South Africa's electricity utility, ...
Developing ESCO procedures for large telecommunication facilities using novel simulation techniques
(North-West University, 2006)
Peak electricity demand in South Africa will exceed the available operational generation
capacity in 2007. The state utility Eskom is addressing this challenge, inter aha, with the
implementation of the Demand-side ...
Investigating the feasibility of braking energy utilisation on diesel electric locomotives for South African Railway Duty Cycles
(2015)
Five modes of transport exist on earth; 1) road, 2) sea, 3) rail, 4) air, and 5) pipeline. Railways have been used for centuries as a means of terrestrial bulk transportation due to its inherent low cost per tonne. ...
Multi-quadrant performance simulation for subsonic axial flow compressors
(North-West University, 2007)
The emergence of closed-loop Brayton cycle power plants, such as the PBMR, resulted in the need to simulate start-up transients for industrial multi-stage axial flow compressors operating at subsonic conditions. This implies ...
Simulation of the sulphur iodine thermochemical cycle
(North-West University, 2011)
The demand for energy is increasing throughout the world, and fossil fuel resources are diminishing. At the same time, the use of fossil fuels is slowly being reduced because it pollutes the environment. Research into ...
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 ...
Development and evaluation of an R–744 evaporator model
(North-West University, 2013)
In recent years carbon dioxide (CO2, R-744) has moved to the foreground as an environmentally friendly alternative to commonly used CFCs and HFCs, which are being phased out due to its high ozone depleting and global warming ...
A conceptual study of a natural circulation cooling loop for a PWR containment
(North-West University, 2011)
The removal of heat from the containment building is an important consideration in the design of a
nuclear power plant. In this investigation a simple rectangular natural circulation loop was simulated to
determine whether ...
Design of a small antenna for indoor electronic monitoring
(2011)
The objective of this project is to design an antenna for use in the electronic monitoring
of persons convicted of non-violent crimes. If implemented, electronic monitoring will
lighten the load on the South African ...
