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 ...
Simulating operational improvements on mine compressed air systems
(North-West University (South Africa). Potchefstroom Campus, 2018)
As the operational costs of deep-level mines increase and gold ore grades decrease, profitability
in the South African gold mining sector is becoming a challenge. Electricity tariff increases
moreover contribute to the ...
Development of a dewatering control strategy to prevent flooding within deep-level mines
(North-West University (South Africa)., 2022)
Deep-level mines are faced with continually increasing challenges regarding heat. New mining depths are constantly reached, and working conditions are becoming intolerable and unsafe. Underground conditions must be controlled ...
Evaluating the feasibility of integrating mine compressed air systems for energy savings
(North-West University (South Africa), 2021)
The South African metals and mining industry is under pressure to increase their production output. While South Africa’s production trend has been decreasing, even though it is the third largest gold reserve, the global ...
Optimisation of mine secondary fan systems
(North-West University (South Africa)., 2020)
The rising cost of electricity in South Africa has driven deep-level gold mines to save on costs. The optimisation of mine ventilation systems has shown significant potential for energy savings. A literature study showed ...
A method for transient simulation of integrated ventilation and cooling systems in deep-level mines
(North-West University (South Africa)., 2022)
Mine ventilation and cooling systems ensure adequate air temperature and flow in underground working areas. These are large and complicated systems that are integrated and interdependent. As underground mines expand to ...
Simulation of the human energy system
(North-West University, 2002)
Preface - Biotechnology is generally accepted to be the next economical wave of the future. In order to attain the many benefits associated with this growing industry simulation modelling techniques have to be
implemented ...
Simulation of natural circulation in an air-cooled Reactor Cavity Cooling System using Flownex
(2014)
Nuclear reactors with improved safety concepts are currently being studied within the nuclear engineering community, with a focus on passive safety features. One of these reactor concepts is the Very High Temperature ...
New concepts for managing diabetes mellitus
(North-West University, 2003)
Preface - Biotechnology is generally considered to be the wave of the future. To facilitate accurate and rapid development of medication and treatments, it is critical that we are able to simulate the human body. One section ...
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 ...
