This thesis reports the results of a detailed programme of research on airblast atomization carried out using a specially
designed atomizer in which the liquid is first spread into a thin sheet and then exposed on both ...
Recent progress in the field of Active Controls Technology(ACT) has resulted in increased interest in dynamic wind tunnel testing for basic research. The present work reports the
findings of a three year research and ...
A sail of 0.3m x 0.28m, with 1% slack, was placed in the test section of a wind tunnel. Both surface visualization and pressure distribution tests were undertaken with the sail at various angles of attack, oc , relative ...
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, ...
An attempt has been made, in this work, to design an efficient, linear—elastic and elasto-plastic, fracture mechanics package based upon finite and boundary element methods. The package contains many useful facilities such ...
Handheld electrically driven spinning disc atomisers are
capable of applying pesticides more efficiently than with
hydraulic nozzles, because the narrower droplet spectra they
produce leads to reduced drift and wastage ...
A new high resolution, space marching, numerical method, based on operator splitting, for high speed, steady, planar two dimensional, Inviscid, chemically reacting (real gas) flow fields as described. A simple model for ...
Fault diagnosis forms an essential component in the design of highly reliable distributed
computing systems. Early models for diagnosis require a global observer, whereas the
diagnosis is shared between the systems nodes ...
Many nations worldwide have been influenced by the experience of the USA in airline deregulation and have begun to consider the reform of their own governmental regulations. However, airline deregulation has both advantages ...
The aim of this research was to devise an innovative technique to
obtain an objective assessment of the quality performance of tubular cored
wires by sensing and measuring the signals available during welding. The
work ...
This thesis addresses the problem of facilitating technology transfer to SMEs (Small and Medium Enterprises). The research sets out to explore the existing body of knowledge relating to the problem, and then by means of ...
A novel gel-filled electrochemical hydrogen probe was developed and used to
measure hydrogen concentrations in carbon-manganese steels. The results were
compared with those from an electrochemical permeation technique ...
The steam lines in the majority of power stations
operating in the UK were fabricated from kCrkMokV steam
pipe material joined using 2CrMo weld metal. Throughout
the life of these systems, which operate typically at
565°C ...
This work is concerned with the design of a pitch-rate-command-attitude-hold command and stability augmentation system in order that the augmented aircraft meets the Gibson dropback criterion, the Gibson phase-rate criterion ...
Subsea pipelines, as the main transportation means for oil and gas produced offshore, are a key element of the production system. Cathodic protection
systems (CPS) are used in combination with surface coatings to protect ...
This project investigates the possibility of using abrasive water jets for cutting operations inside oil wells and presents the associated procedures and tools required. Through-tubing window cutting was identified as an ...
This thesis considers the neural network learning control of a variable-geometry
automotive active suspension system which combines most of the benefits of active
suspension systems with low energy consumption.
Firstly, ...
To further enhance the progress made by its manufacturing industries during the last two decades, the Sixth Development Plan of Saudi Arabia has stressed the importance of diversifying the country’s economic base, reducing ...
Thin Film Bulk Acoustic Wave Resonators (FBAR) are mechanical micro scale devices
that operate in the UHF/Microwave frequency range. This high frequency of operation
potentially offers increased sensitivity to the addition ...
This thesis presents a dynamic analysis and a control system for a flexible space
manipulator, the Deployable Robotic Manipulator or DRM, which has a
deployable/retractable link. The link extends (or retracts) from the ...
