Heat and mass transfer model for a coffee roasting process
(North-West University (South Africa) , Potchefstroom Campus, 2017)The roasting of coffee is a complex process and it takes years of experience to be able to produce a quality cup of coffee (as well as consistently reproducing the same quality coffee). Although there are various factors ... -
Heat transfer phenomena in flow through packed beds
(North-West University, 2006)In order to simulate the thermal-fluid performance of a pebble bed reactor such as the PBMR, heat transfer phenomena in packed beds must be characterized. In the pseudo-heterogeneous simulation approach that is often ... -
A heterogeneous Thorium-based fuel design for a PWR aimed at increasing fuel cycle length
(2015)A new heterogeneous Thorium based fuel design has been proposed for Pressurised Water Reactors in order to increase fuel cycle lengths. This design incorporates ThO2 pellets which have been included between UO2 fuel pellets ... -
A high precision driver for an eddy current displacement sensor
(North-West University, 2009)This dissertation presents the design and development of a high precision driver for an eddy current displacement sensor. The project was initiated to supplement the development of a low-cost PCB eddy current displacement ... -
High pressure water supply strategy for mine bulk air coolers
(North-West University (South Africa)., 2022)South African gold mines face many challenges with rising production costs being amongst the biggest concerns. Labour unrest and low economic growth along with increased production costs are affecting the productivity and ... -

(North-West University (South Africa), 2020)Hydrogen, as energy carrier, is expected to play an indispensable role in the future energy prospects. Subsequently, significant advancements in research and development of hydrogen-based technologies, in the areas of low ... -
High-performance sailplane airbrake analysis using CFD
(North-West University (South Africa)., 2023-10)Sailplane airbrakes are an essential part of sailplane control and safety. So much so that EASA, (European Aviation Safety Agency) has specific regulations specifically aimed at sailplane airbrake design. For sailplanes ... -
A holistic approach to evaluate the feasibility of implementing ice thermal storage on deep mines
(North-West University (South Africa), 2020)Over the past decade, the mining industry has been faced with several challenges that have contributed towards dwindling profit margins across many South African deep-level mines. One of the major, if not the most significant ... -
Holistic evaluation of surface cooling plant configurations for different seasons at deep mines
(North-West University (South Africa)., 2023)The mining sector consumes a large portion of South Africa’s electricity. Deep mining contributes to 15% of the total electricity consumption in South Africa. Mining electricity costs in South Africa have increased by 655% ... -
Human Capital Evaluation : determining both the cost and value of a firm's human
(North-West University (South Africa)., 2021)Many times, the phrase “our people are our most important asset” is used by company CEO’s. Yet personnel are not included on the balance sheet of any company. There are several reasons for this, including the fact that ... -
A hybrid system for condition based maintenance in nuclear power plants
(North-West University (South Africa), 2020)Condition-based maintenance (CBM) involves undertaking maintenance activities based on the health of the system. Establishing a CBM regime in an industry will result in eliminating unnecessary maintenance cost without ... -
