• Nagraadse programleier/s word aangestel binne elke skool om na die nagraadse programinhoud om te sien.

• 'n Navorsingsdirekteur staan aan die hoof van die Navorsingsfokusarea. Die navorsingsdirekteur is verantwoordelik vir alle aspekte rondom navorsing.

• Akademiese personeel kan deel wees van die fokusarea as deelnemers, gedefinieër as personeel wat navorsingsuitsette lewer, en/of as nagraadse studieleiers.

• Studieleiers neem direk verantwoordelikheid vir die navorsingskomponent van hul eie nagraadse studente, binne spesifieke sub-programme.


Nagraadse programme

Meestersgrade: Toelatingsvereistes

M.Ing program

Die M.Ing graad is 'n graad wat volg op 'n vier-jarige ECSA-geakkrediteerde Baccalaureusgraad in Ingenieurswese.

M.Sc (Ingenieurswetenskappe) program:

Die M.Sc in Ingenieurswetenskappe volg op 'n B.Sc (Hons) graad of 'n vierjarige Baccalaureus in Ingenieurswese or 'n ander erkende kwalifikasie wat aan die student ekwivalente status verleen en wat goedgekeur is deur die Nagraadse Navorsingskwaliteitsversekeringskomitee.

In sommige gevalle en op diskresie van die fakulteitsbestuur, kan studente deur 'n proses van "Erkenning van Vorige Leer" toelating kry tot een van bogenoemde programme, waar daar nie aan die toelatingsvereistes voldoen word nie.

WANNEER MOET EK REGISTREER?

Registrasie vind gewoonlik vanaf Februarie plaas. Nuweling nagraadse studente word toegelaat om te registreer tot einde Junie MAAR geen student mag lesings bywoon as hy/sy nie geregistreer is nie. Dit is dus beter om so vroeg as moontlik te registreer.

NB: Nagraadse studente moet elke jaar weer registreer (teen einde Maart van die betrokke jaar).

5. Navorsingsmetodiek (alle opsies)

Navorsingsmetodiek is 'n verpligte module vir alle M-studente.

Vanaf 2007 is daar een kontakgeleentheid aan die begin van die jaar, en daarna werk die student saam met sy/haar studieleier om uiteindelik 'n navorsingsvoorstel gereed te kry.

6. Klasroosters/modules (opsies B en C)

Modules word voor registrasie met die studieleier en/of nagraadse programbestuurder uitgeklaar. Die modules word deur die onderskeie SKOLE bestuur, terwyl die navorsing deur die onderskeie NAVORSINGSFOKUSAREAS bestuur word. Klasroosters is by die onderskeie skoolsekretaresses beskikbaar.

Description/ Beskrywing Hierdie projek handel oor die elektromagnetiese ontwerp van 'n lae-spoed, hoë-draaimoment PMSM met 'n aandrywingstelsel. Die tipiese toepassings van so 'n masjien indien hy as motor gebruik word is in traksie (swaar voertuie wat stadig beweeg, bv. industriële en mynbou voertuie wat swaar materiaal moet skuif, groot skepe, ens.) Vir toepassing as generator kan so 'n masjien gebruik word as direkte-aandrywing windgenerator (d.i. sonder die ratkas wat by konvensionele hoë-spoed masjiene benodig word). Die uitdaging in so 'n ontwerp is die haal van 'n hoë koppeldighteid [Nm/m3] en spesifieke koppel [Nm/kg]. Die fokus van die projek is op die masjienontwerp, maar 'n werkende aandrywingstelsel sal benodig word om die masjien te toets, en vorm dus deel van die projek. (Die aandrywingstelsel kan in samewerking met ander lede van die navorsingsgroep ontwikkel en gebou word, of selfs deur 'n buite-kontrakteur gedoen word.) 'n Skaalmodel van 'n masjien en aandrywing sal afgelewer word na afloop van die studie.

Project Title/ Projektitel Evaluating the impact of CO2 on heat pump performance.


Supervisor / Studieleier M van Eldik and Prof PG Rousseau



Description/ Beskrywing Due to the international phase-out of refrigerants classified as harmful to the environment, research has focused on finding alternative refrigerants. One of the alternatives identified is CO2 which is a by-product of chemical processes. The major advantage of using CO2 compared to existing refrigerants applied in water heating heat pumps is that higher outlet water temperatures can be obtained. High water temperatures, in the region of 90°C, have ample industrial process applications. This combined with the high efficiency of a heat pump will supply the industry with an energy efficient solution. The purpose of this study will be to investigate the impact of CO2 as working fluid on the overall heat pump performance. This project will require of the candidate at Masters degree level to:

• Conduct a detailed investigation into the current state of CO2 technology focusing on heat pump applications.

• Set up simulation models for each individual component in the heat pump cycle using Engineering Equation Solver (EES).

• Integrate the individual models into a CO2 heat pump system model.

• Validate the simulation models through comparison with empirical data found in the literature.

• Apply the simulation model to investigate and evaluate the overall heat pump performance.

• Encapsulate the results in a manner that can be useful to heat pump designers.

Project Title/ Projektitel Investigation into the friction factors and Nusselt numbers for laminar flow in ducts


Supervisor / Studieleier Prof CG du Toit


Description/ Beskrywing The determination of the wall shear stress and the heat flux at the wall of a duct is of utmost importance in the analysis and design of, for example heat exchangers, which play a significant role in numerous applications. The friction coefficients and the heat transfer coefficients needed in the design and analysis process to calculate the wall shear stress (and subsequently the pressure drop) and the heat flux, are normally obtained from the friction factors and Nusselt numbers respectively for the various duct sections which may be encountered in practice. This project will require of the candidate at Masters degree level to:

• Collect and study the relevant literature on the subject. • Familiarize himself / herself with the various analytical solutions

that have been developed for a number of cases. • Make use of existing finite element codes to model the above

mentioned cases numerically. Where necessary the codes must be adapted.

• Employ the finite element codes to determine the friction factors and Nusselt numbers for a selection of cases where no analytical solutions are available.

Project Title/ Projektitel Evaluation of the impact of evaporator circuiting on heat pump performance


Supervisor / Studieleier Prof PG Rousseau and M van Eldik


Description/ Beskrywing It is well-known that overall counterflow circuiting provides the highest values of effectiveness in most finned-tube heat exchangers. However, in the case of direct expansion evaporators this may not always be the case. The reason for this is that the pressure drop on the refrigerant/tube side could result in inverted temperature gradients in some sections of the heat exchanger. This effect can become very pronounced in the case of zeotropic refrigerant mixtures and could possibly be exploited to provide useful improvements in heat exchanger effectiveness. The purpose of this study will be to investigate the effects of more intricate evaporator circuiting configurations on overall heat pump performance for different refrigerant types including R22 and R407C. This project will require of the candidate at Masters degree level to:

• Study the relevant circuiting methodologies and existing heat exchanger simulation models and data.

• Set up detailed discretized simulation models for direct expansion evaporators allowing a variety of intricate circuiting arrangements and refrigerants.

• Integrate the evaporator model in a simplified heat pump system model.

• Validate the simulation model through comparison with existing empirical data and where necessary generate additional empirical data with the aid of an existing heat pump test bench.

• Apply the simulation model to investigate and evaluate the effects of different circuiting arrangements on overall heat pump performance.

• Derive useful design guidelines or a design methodology to encapsulate the results in a manner that can be useful to heat pump designers.

Project Title/ Projektitel Combined low loss permanent magnet biased active magnetic bearing

Reference / Verwysing NC001

Supervisor / Studieleier Prof. G. van Schoor (Supervisor); Mr. E.O. Ranft (Co-supervisor)


Description/ Beskrywing The MBMC Research Group is in the process of developing a high speed flywheel energy storage system. Since high efficiency is one of the basic requirements of a flywheel energy storage system, the use of low loss bearings is essential. Low loss Active Magnetic Bearings (AMBs) are used to suspend the flywheel rotor in a vacuum. The development of a low loss AMB utilising permanent magnets for biasing is proposed. Since two radial and one axial AMB are required in such a system, the one radial AMB and the axial AMB can be combined to better utilise space and magnetric material. The design of such a combined AMB is also part of this project.

Project Title/ Projektitel The Design of Catcher Bearings for AMB Supported Rotors


Supervisor / Studieleier Mr. J.G Roberts (Supervisor); Prof. G. van Schoor (Co-supervisor)


Description/ Beskrywing Rotors supported on Active Magnetic Bearings (AMB’s) require catcher bearings to support the rotor when the AMB controller is off and to prevent excessive damage of the machine in case the AMB system fails. The catcher bearings typically consist of low friction bushes located close to the AMB with a radial air gap of approximately half the magnetic air gap of the AMB. Another design uses rolling element bearings with inertia disks to retard the spin-up rate of the rolling element bearing. The emphasis of this M-study is to establish the design methodology and to define the required tools for designing the catcher bearings of an AMB supported rotor. This methodology shall be applied to the redesign of the catcher bearings of the Fly-ups rotor, provided all the design tools can be afforded. The student shall do low risk rundown tests on catcher bearings to learn more about the behaviour of the rotor supported on catcher bearings.



Project Title/ Projektitel Determination of the Windage Losses of the flywheel UPS Rotor


Supervisor / Studieleier Mr. J.G Roberts (Supervisor); Prof. G. van Schoor (Co-supervisor)


Description/ Beskrywing A number of theories exist to predict the windage loss of rotating cylinders and disks. However, the variance in these predictions is so large that windage losses cannot be predicted accurately enough with presently publicized theory. The Fly-ups rotor is an application of Active Magnetic Bearing (AMB) Design that consists of a combination or rotating cylinders and disks with varying air gaps. The density of the air can be adjusted by controlling the vacuum around the rotor. Other gasses could also be used to investigate the effect of viscosity of the fluid on the accuracy of the predictions. The emphasis of this M-study is on the theory to predict windage of a typical rotor supported in AMB’s sufficiently accurate by experimental measurement of the windage torque. The student shall devise a method to measure windage in the most cost effective way.

Supervisor / Studieleier Prof. G. van Schoor (Supervisor); Mr. J.G. Roberts (Co-supervisor)


Description/ Beskrywing The MBMC research group is amongst others striving towards a comprehensive modelling platform for the design of active magnetic bearing (AMB) systems. Up to date the AMB models only included the AMB as such and did not include any rotordynamic effects. The purpose of this project is to establish the impact of rotordynamics on system performance and its impact on AMB requirements. The inclusion of the rotordynamics into the design platform will significantly enhance system design integrity. The model performance will be verified with practical measurements and analytical analyses.




Project Title/ Projektitel State-space modelling of thermo-hydraulic systems based on Bond graphs


Supervisor / Studieleier Prof. G. van Schoor (Supervisor); Mr. KR Uren (Assistant supervisor)


Description/ Beskrywing Bond graph theory was developed by H.M. Paynter in the 1960’s. The basic idea behind Bond graphs is to create a visual representation of the power flow through a system. By developing a power flow diagram and adding causal assignments identifying the causal relationships between state variables, creating equations describing the systems’s dynamic behaviour becomes a relatively straightforward task. The compact nature of Bond graphs lends it extremely well for computer-aided modelling. This distinguishes Bond graph modelling from other techniques as potentially the most useful systematic modelling technique. The project will be concerned with deriving low-order state-space models of thermo-hydraulic systems by applying bond graph theory. The state-space representation is preferred for modern controller design methods such as model predictive control. Computer modelling software such as Symbols 2000, Matlab and Simulink will be utilized.

It’s main strengths lie in problems that has a large number of control variables, changing control objectives, constraints on control variables and time delays. MPC leads to an optimization problem wich is solved on-line in real time at each sampling interval. An existing state-space model of the power conversion unit of the PBMR is available. The poject will involve the application of MPC on this state-space model. This study will contribute in exploring the possibility of using MPC as an automatic controller design technique. Matlab has a MPC toolbox which provides a graphical interface for designing MPC controllers. This toolbox along with Simulink will be used to develop and analyze MPC controllers.

Supervisor / Studieleier Mr. J.G. Roberts (Supervisor)


Description/ Beskrywing Two failure theories are proposed for design of graphite structures for nuclear reactors. The first is the KTA rule that is based on Maximum Deformation Energy equivalent stresses and a modified Weibull distribution that determines the probability of failure of a component. The second is the CARES/Life criterion, developed by NASA, that uses a Weibull distribution to determine the probability of failure of a component. The main focus of this research is to evaluate the accuracy of these failure criteria by using publicized failure data. Static uniaxial as well as multiaxial failure data shall be used in this research.

Project Title/ Projektitel Evaluation of the effective conductivity through a packed pebble bed due to radiation and point contact conduction


Supervisor / Studieleier Proff PG Rousseau and CG du Toit


Description/ Beskrywing The High Temperature Test Unit (HTTU) forms part of the PBMR Heat Transfer Test Facility (HTTF). One of the tasks that will be performed on the HTTU is the evaluation of the effective conductivity through the packed pebble bed structure at high temperatures, due to radiation and point contact conduction between the pebble surfaces. This phenomenon forms an integral part of the mechanism that allows for an inherently safe pebble bed nuclear reactor design. This project will require of the candidate at Masters degree level to: • Study relevant existing correlations and empirical data. • Take part in the planning and execution of the actual measurements of

effective conductivity. • Do the data reduction and associated theoretical analyses necessary to

assess the results. This project will require of the candidate at Doctoral degree level to: • Study relevant existing correlations and empirical data. • Identify what novel contribution can be made to address possible
