An evaluation of a design method for mixed flow fans
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Mixed flow fans find application in an operating region between that of axial flow and
centrifugal fans. The candidate investigated the working of these mixed flow fans and
formulated a design algorithm. ...
Computational and experimental investigation of chamber design and combustion process interaction in a spark ignition engine
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The automotive industry in South Africa is expanding as a result of pressure on the
world economy that forces vehicle manufacturers to outsouree work to developing
countries. In order to add value to ...
Performance of a solar air heater incorporating thermal storage
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: In the present study, research was conducted to determine the
feasibility of water energy storage through which the output of
heated air by an upward facing solar air heater could be prolonged.
Following ...
Helicopter tail boom vibration analysis and suppression
(Stellenbosch : Stellenbosch University, 2002-04)
ENGLISH ABSTRACT: An experimental investigation was conducted usmg a cantilever beam to illustrate an
understanding of vibration techniques and phenomena. The [Tee and forced vibration of the
cantilever beam was ...
Modeling of internal combustion engine thermodynamics, valve dynamics and valve flow
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: In the design or modification of internal combustion (IC) engine
components, the South African Automotive industry has always relied on
either design by mother companies or quasi-empirical design ...
Semi-automatic extraction of primitive geometric entities from point clouds
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: This thesis describes an algorithm to extract primitive geometric entities (flat planes,
spheres or cylinders, as determined by the user's inputs) from unstructured,
unsegmented point clouds. The ...
The effect of turbo-charging and intercoolingon emissionsgeneration [i.e. intercooling on emissions generation] and durability of a diesel engine
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: To reduce exhaust gas emissions in diesel engines and for engine upgrade purposes the
major parameters and equipment that should be looked at are boost pressure, intake
charge temperature, combustion ...
Simulation of a syngas from coal production plant coupled to a high temperature nuclear reactor
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: In light of the rapid depletion of the world’s oil reserves, concerns about energy
security prompted the exploration of alternative sources of liquid fuels for
transportation. One such alternative is ...
Development,testing and fluid interaction simulation of a bioprosthetic valve for transcatheter aortic valve implantation
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: Bioprosthetic heart valves (BHVs) for transcatheter aortic valve implantation (TAVI) have been rapidly developing over the last decade since the first valve replacement using the TAVI technique. TAVI is ...
Performance and thermo-mechanical cost evaluation of API 661 air-cooled heat exchangers
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: The optimal design of a heat exchanger for a specified heat transfer, pressure drop
and set of ambient conditions entails minimising space, weight, material usage and
overall cost. However, the variables ...
