-
(University of Pretoria, 2006-06-03)Due to a relative high thermal efficiency, the gas turbine engine has wide ranging applications in various industries today. The aerospace and power generation sectors are probably the best known. One method of increasing ...
-
(University of Pretoria, 2006-06-03)Interaction of various components in rotating machinery like gearboxes may generate excitation forces at various frequencies. These frequencies may sometimes overlap with the frequencies of the forces generated by other ...
-
(University of Pretoria, 2007-01-24)In the rally car racing there is a need for maximum power throughout the race. While this is not possible through the entire engine speed range, it is possible to manipulate the engine speed at which maximum power is ...
-
(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, 2006-01-24)The purpose of this study is to perform an investigation of the numerical methods that may contribute to the design and analysis of liquid containers. The study examines several of these methods individually, namely ...
-
(University of Pretoria, 2012-05-21)Mathematical and computer modelling have been playing an increasingly important role in the Computer Aided Engineering (CAE) process. Simulation offers great advantages in the development and analysis phase of products and ...

-
(University of Pretoria, 2007)In this two-part study, developments in finite element technology and the application thereof to topology optimization are investigated. Ultimately, the developed finite elements and corresponding topology optimization ...
-
(University of Pretoria, 2007)The micro-electromechanical systems (MEMS) industry has grown incredibly fast over the past few years, due to the irresistible character and properties of MEMS. MEMS devices have been widely used in various fields such as ...

-
(University of Pretoria, 1999)In this thesis, techniques for testing aircraft models in ground effect in a low speed wind tunnel are investigated. Although these types of tests have been done before, the current study is unique in that forces are ...
-
(University of Pretoria, 2012-10-01)This work details the development of a computational tool that can accurately model strongly-coupled fluid-structure-interaction (FSI) problems, with a particular focus on thin-walled structures undergoing large, geometrically ...
-
(University of Pretoria, 2010)This study proposes novel optimization methodologies for the optimization of problems that reveal non-physical step discontinuities. More specifically, it is proposed to use gradient-only techniques that do not use any ...
-
(University of Pretoria, 2008-07-11)Acute Liver Failure (ALF) is a devastating ailment with a high mortality rate and limited treatment alternatives. This study presents a methodology for the design and development of a bio-artificial bioreactor to be used ...
-
(University of Pretoria, 2008-04-24)Gas turbine combustion chambers were traditionally designed through trial and error which was unfortunately a time-consuming and expensive process. The development of computers, however, contributed a great deal to the ...
