Numerical optimisation methods have successfully been used for a variety of aerodynamic design problems over quite a few years. However the application of these methods to the aerodynamic blade shape optimisation of ...

This thesis describes the development of an ElastoHydroDynamic (EHD) bearing calculation. The effect of body forces is shown to be important for highly loaded bearings in reciprocating internal combustion engines. Extension ...

This thesis presents an experimental investigation and identifies the feasibility of the use of AE technology to detect and monitor both early stage bubble occurrence and throughout the boiling process. The research programme ...

Hydrokinetic tidal turbines are devices for which the relative importance of the incoming flow on fatigue life is higher when compared to wind generators. This is due to the difference in density between the two fluids and ...

With the current growth rate of world population, comes a high demand on electric energy generation. Technological advancements in metallurgy, fuel conversion, heat transfer, and turbomachinery design allow the continuous ...

Different tidal power generating systems have been studied for a long time. DeltaStream, which has been under development by Tidal Energy Limited has as a salient feature the fact that it is a tubular structure, equilateral ...

The thesis describes a set of studies carried out in parallel with a tidal turbine design program which was undertaken by the Turbomachinery Group to which the author belonged to during the duration of this project. ...

Tidal turbines operate in marine currents characterised by strong turbulence. This environment impacts on the life of the device, blades, transmission and running train ancillaries, bearings and seals, for example. The ...
