The literature available on the effect of vessel geometry, particle properties and liquid
properties on the distribution of solids in a mechanically stirred vessel has been
examined. This has shown that there are wide ...
An investigation was made into the corrosion of steel immersed in
seawater by electrochemical (LPR scans) and weight loss
techniques. Steel samples in the form of studs or a specially
designed corrosion probe were ...
Unfettered competition in the US and Canada has resulted
in a much more efficient airline industry, but the considerable
economies derived from the resulting structural change has lead
to greater levels of concentration ...
This thesis describes both theoretical and experimental
work performed in order to study the fatigue- crack
propagation behaviour of the 7075 T7351 Aluminium - Zinc
alloy, under constant and variable amplitude loading.
For ...
The flow inside a vortex controlled diffuser was studied experimentally and theoretically. The experimental side of the study included the following:
(1) The selection of a suitable laser Doppler velocimeter for the ...
This thesis describes an experimental study and discussion of gas/liquid/liquid and liquid-liquid pipe flow, where the principal objective was to collect three-phase flow data and treat this data by modified gas-liquid ...
Wavelength division multiplexed arrays of in-fibre Bragg gratings (IFBGs)
are fabricated in hydrogen loaded optical fibres. The IFBG arrays are embedded into a
carbon fibre composite test beam for the purpose of quantitative ...
Many computational problems of theoretical and practical
interest are not naturally bounded by physical boundaries.
Aerodynamic examples include flow calculations past aerofoils or past
wing-body configurations, ...
This thesis describes both experimental and theoretical work performed
in order to analyse fatigue fracture in the presence of shot-peening
induced residual stresses.
In the study, four contrasting alloys were examined ...
This work dealt with elasto-plastic analysis of 2-dimensional and
axisymmetric problems using the finite-element and boundary-element
techniques. The analysis is based upon a vide range of yield
criteria and hardening ...
The orifice meter is still commonly used for natural gas measurement despite its
many limitations. Considerable efforts in recent years have resulted in improved
knowledge of factors such as installation effects and the ...
Carneiro, Helder Fernando De Franca Mendes(1993-05)
An Attempt at development of theory and computer program for the solution of
potential and viscous flow problems using the Boundary Element Methods is
introduced in this work. A program for potential flow analysis of ...
Mechanical seals are used extensively on rotary applications where the sealed fluid is under pressure. They may rightly be considered to be generally reliable and trouble free, many giving lives of over 3 years. However, ...
Fracture and toughening mechanisms in rubber modified and hybridized urethane-methacrylate
resins have been investigated. Fracture mechanisms are defect-dominated in the unmodified
resin. The relationships between defect ...
The influence of process parameters on deposition and fusion
characteristics of mild steel with Pulsed Gas Metal Arc Welding has
been investigated using a transistorized power supply.
A simple model of melting behaviour ...
The dispersion of air into water was studied in a tall agitated vessel (ungassed liquid
depth = 2.4 x vessel diameter) fitted with four different triple impeller combinations:
1. Three identical Rushton turbines
2. One ...
This thesis is a description of an experimental study of gas-liquid
dispersion in mechanically agitated vessels. The objectives of the
project were to investigate scale-up and to compare different
agitator types. Three ...
Heat pipe heat exchangers (HPHEs) offer many advantages over other types of
heat exchangers for the recovery of heat from industrial gaseous waste streams in
the low and medium temperature ranges. Heat pipes employed in ...
This research has been concerned with the oxidation
and corrosion of iron and mild steels, with particular
reference to the importance of the mechanical properties
of the surface oxides formed. A vibration technique ...
The basic properties of arcs in flowing ga-,es, minimum
ignition energy and quenching distances are the\focal points of this
research. The flow parameters turbulence, pressure, velocities, fuel-air ratio etc. are varied ...
