(University of Pretoria, 2016)The interaction between tyres and terrain is one of the most studied areas in the vehicle dynamics and terramechanics research communities because it is the only region where excitation forces act on the vehicle if ...
-
(University of Pretoria, 2015)This document focuses on the procedure and results of creating a thermohydraulic model of the secondary cooling system of the SAFARI-1 research reactor at the Pelindaba facility of the South African Nuclear Energy Corporation ...
-
(University of Pretoria, 2017)This aim of this project may be condensed to the following question: Is there an improvement achievable in the braking performance of a vehicle on a rough road? Several follow-up questions arise from the above problem ...
-
(University of Pretoria, 2018)Anti-lock braking systems (ABS) have revolutionised vehicle safety by providing a mechanism for braking effectively whilst maintaining stability control. ABS works very well on smooth terrains, where there are little ...
-
(University of Pretoria, 2020)The compromise between ride comfort and handling for a passive suspension system is a well-known and often researched problem. Semi-active suspension systems offer significant improvements to this compromise. One example ...
-
(University of Pretoria, 2014)Diagnostics and prognostics in rotating machinery is a subject of much on-going research. There are three approaches to diagnostics and prognostics. These include experience-based approaches, data-driven techniques and ...

(University of Pretoria, 2007-06-28)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2014)Iterative learning control (ILC) is a repetitive control scheme that uses a learning capability to improve the tracking accuracy of a desired test system output over repeated test trials. ILC is sometimes used in response ...
-
(University of Pretoria, 2017)Secondary flow structures account for nearly 50% of aerodynamic losses experienced in the turbine blade passages. The adverse effects of these vortex structures transport the hot mainstream fluid towards the endwall blade ...
-
(University of Pretoria, 2019)Elevated inlet temperature is desirable in turbine passages. This is not without a whole lot of aerodynamic loss, endwall thermal stresses consequences and pressure loss penalties most especially downstream of the turbine ...
-
(University of Pretoria, 2022)A recuperated solar-dish Brayton cycle using an off-the-shelf turbocharger as a micro-turbine and a rectangular cavity receiver with integrated thermal storage was considered for this study. Due to the high temperatures ...
-
(University of Pretoria, 2011-10-04)Free-surface modelling (FSM) is a highly relevant and computationally intensive area of study in modern computational fluid dynamics. The Elemental software suite currently under development offers FSMcapability, and employs ...

An investigation on inefficiencies in spare part management processes in South African Power Plants (University of Pretoria, 2018)Inefficiencies in spare parts management can, and do, have great repercussions for the execution of maintenance in Eskom power stations. Despite this, the sub-processes of spare parts management in power stations had not ...

-
(University of Pretoria, 2014)This study focused on a numerical second law analysis and optimisation of a receiver tube op- erating in a parabolic trough solar collector for small-scale application. The receiver functioned in a Rankine cycle. The ...
-
(University of Pretoria, 2006-01-13)The analysis and optimum design of stiffened, shear webs in aircraft structures is addressed. The post-buckling behaviour of the webs is assessed using the interactive algorithm developed by Grisham. This method requires ...
-
(University of Pretoria, 2007-01-24)Spring and damper characteristics determine to a large extent the ride quality and handling of a vehicle. Since the requirements for good ride and good handling are conflicting, adjustable suspension elements are developed. ...
-
(University of Pretoria, 2020)Concentrated solar power is a growing but expensive alternative energy resource. One of the most common issues faced when it comes to solar dish design is the complex trade-off between cost and optical quality. A novel ...
-
Analysis of Conjugate Heat Transfer and Pressure Drop in Microchannels for Different Aspects Ratios (University of Pretoria, 2016)In this study the heat transfer and hydrodynamic parameters were experimentally investigated for a single microchannel housed in a stainless steel solid base material for different aspect ratios in the laminar regime with ...
