The in-flight pressure fuselage failure of an Aloha Airlines Boeing 737 near
Maui, Hawaii on 28 April 1988 brought the issue of Ageing Aircraft and in
particular the dramatic destructive potential of Widespread Fatigue ...
Transonic flows are simulated within convergent
divergent nozzles and within turbomachinery blade rows.
The flow is represented by the conservative full potential
equation approximated by a nine-node central-difference
scheme, ...
Submerged arc weld deposits were produced using a 40 mm thick
low Sulphur, low Phosphorous, Carbon Manganese microalloyed steel
to B»S. 45d0 : 50D. The welding consumables used were a 4 mm diameter
C. 1'2/fc Mn Wire ...
The commercial and operational attractiveness of improving
the specific thrust, whilst minimising the weight, of an
aero gas turbine engine, has inevitably led to the
compressor operating as near to stall as is ...
The developm ent of an optimising model predictive controller for dom estic storage
radiators w as the ultimate goal of this research project. Neural networks are used
to create empirical m odels that are used to predict ...
Hydrodynamic oil film bearings exhibit lateral flexibility which
influences the dynamics of rotors they support. This lateral flexibility is specified by coefficients which relate forces generated by
the oil film to the ...
The literature on the leading edge viscous interaction phenomena has "been reviewed. Theoretical studies of the leading edge bluntness and the boundary - layer displace¬ment effects have been made by using a combination ...
Modern structural steels have significantly different (generally leaner) compositions than equivalent conventional steels developed over 20 years ago. To compensate for the lower carbon and alloy content more sophisticated ...
This thesis presents a theoretical and experimental study
of swirling flow in an orifice plate flowmeter.
Firstly, a solid body rotation was considered as the inlet
velocity profile of an orifice plate. The beta ...
This thesis presents the results of a detailed investigation into the performance of devices
designed to suppress the vortex induced vibration of slender cylindrical structures.
The phenomenon of vortex induced vibration ...
The erosion prone areas on the blade surfaces of a centrifugal impeller handling granular solids have been investigated both theoretically and eperimentally.
The objective of the theoretical study is to develop software ...
The suitability of the octagonally coordinated complex, ruthenium (III) hexamine, as a soluble electron
mediator for glucose oxidase in the electrochemical capillary fill device (CFD) was investigated.
Electrochemical ...
'Low density polyethylene has been oriented into a state of
transverse isotropy by cold-drawing an originally isotropic blank in
uniaxial tension, and the non-linear creep behaviour of the material
has been completely ...
Questions are continually being asked about the direction in which land
based production in the UK is evolving. Present systems are criticised
as being damaging to the wider environment and rural communities. Of
equal ...
In the natural gas market, open access along with gas brokering and marketing
has resulted in multiple gas contracts through one physical measuring point
Accurate metering of natural gas has become more important than ...
The aim of this work is to study the unsteady response of
rotor blades of a lightly loaded single stage axial flow
compressor experiencing inlet flow distortions in forms of
circumferential pressure distortions and ...
The effect of turbulent flow-fields on a premixed flame-front has been of
considerable interest in the field of combustion research. Modern laser diagnostics
allow the measurement of important parameters such as species ...
The suspension system of a ground vehicle moving on or off road
can be improved by so called "active control" using control
strategies which require feedback of all or some of the system
states. A stochastic state ...
Boundary Layer Flows in turbomachines have been recognised to crucially
influence the stability and performance of gas turbine components particularly the
compressor since its function is to provide a pressure rise through ...
The origin of the wind-turbine is discussed and its subsequent
development reviewed.
Various types of sail wind-turbine are described and their
advantages and different types detailed. Their appropriateness for
driving ...
