Characteristics of energetic motions in turbulent boundary layers
In this dissertation, we present the first measurements of two-dimensional (2-D) energy spectra of the streamwise velocity component (u) in high Reynolds number turbulent boundary layers. The measurements in the logarithmic ...
Wood particle based biocomposites consolidated by equal channel angular pressing
Previous research has demonstrated the potential of equal channel angular pressing (ECAP) for producing wood particle based biocomposites. By disturbing wood particle structure and reducing cellulose crystallinity, wood ...
Performance of electricity markets & power plant investments in the transition to a low-carbon power system
In power systems around the world, substantial quantities of Variable Renewable Generation (VRG) sources such as wind and solar are being introduced. Challenges arise from increasing VRG as it is characterised by significant ...
Experimental investigation of velocity and vorticity in turbulent wall flows
This thesis details the results of a research effort both to acquire sufficiently-resolved velocity and vorticity vector time-series in turbulent wall-bounded flows, as well as to use the acquired data to juxtapose two ...
Autoignition of pentane isomers in a spark-ignition engine: experiment & modeling uncertainty quantification
Pentane isomers are among the most abundant constituents of worldwide gasoline. Their autoignition has been extensively studied in fundamental reactors (shock tube, rapid compression machine (RCM), jet-stirred reactor, ...
Multimedia training facility for high speed machining
Change has now become a fact of life in all businesses, and training is no exception to the rule. (Leigh, 1996)
Sustainable technology transfer for small to medium enterprises in developing countries
Technology transfer has been well recognised as a means to advance technology capability. Numerous organisations world-wide have been involved in technology transfer programs. Transnational and domestic technology transfer ...
Mass reduction of fatigue-limited, safety-critical (FLSC), ferrous metal automotive components by forged light alloy substitution
The substitution of ferrous metal with forged light alloys in Fatigue-Limited, Safety- Critical (FLSC) applications provides an opportunity to achieve mass reduction. However, the use of forged light alloys in FLSC ...
Design of a prosthetic anterior cruciate ligament
Injury to the knee can have a dramatic effect on a person's lifestyle. Participation in sports and exercise, general mobility, and even commonplace activities like walking up stairs can all be restricted or prevented ...
Mechanical alloying, thermal stability and consolidation of Al-5 at.% Nb alloy
High energy mechanical alloying, a non-equilibrium processing method was successfully employed to extend the solid solubility of Al-5 at.% Nb alloy. Microstructural evolution with varying milling duration was studied in ...
