Tapered optical fibre sensors employing nanostructured coatings

Jarzebinska, Renata (Cranfield University, 2010-05)

Tapered optical fibres have been manufactured, characterised and studied. These are compact devices made from single-mode optical fibre. A system for producing tapers has been developed, employing flame heating of the ...
Techniques for the evaluation of wastewater treatment process

De Bel, M. (Cranfield University, 2001-11)

This study focussed on extending and applying techniques to measure hydrodynamic characteristics in treatment units at sewage works. Use was made of tracer dye studies and a spreadsheet based analysis tool. The resulting ...
Techno-economic analysis of compressed air energy storage systems

Bozzolani, Emanuele (Cranfield University, 2010-11)

The continuous escalation of intermittent energy added to the grid and forecasts of peaking power demand increments are rising the effort spent for evaluating the economic feasibility of energy storages. The aim of this ...
Techno-Economic Analysis of Gas Turbine Compressor Washing to Combat Fouling

Abass, Kabir Oliade (Cranfield University, 2015-03)

Among the major deterioration problems a gas turbine encountered while in operation is compressor blade fouling. This is the accumulation and adhesion of dirt and sediment on the compressor blade which contributes between ...
Techno-economic and environmental risk assessment of innovative propulsion systems for short-range civil aircraft

Colmenares Quintero, Ramon Fernando (Cranfield University, 2009-04)

Aircraft are thought to contribute about 3.5% (IPCC, 1999) to the total radiative forcing (a measure of change in climate) of all the human activities and this figure is forecaste to increase. Future concerns for aviation’s ...
Techno-economic environmental assessment of advanced intercooled propulsion systems

Najafi Saatlou, Esmail (Cranfield University, 2012-09)

A tool based on a Techno-economic and Environmental Risk Assessment (TERA) framework is useful at the preliminary stage of an aero engine design process, to conceive and assess engines with minimum environmental impact ...
Techno-economic studies of environmentally friendly Brayton cycles in the petrochemical industry

Nkoi, Barinyima (Cranfield University, 2014-10)

Brayton cycles are open gas turbine cycles extensively used in aviation and industrial applications because of their advantageous volume and weight characteristics. With the bulk of waste exhaust heat and engine ...
Techno-economic study of gas turbine in pipeline applications

Nasir, Abdulkarim (Cranfield University, 2013-03)

Natural gas being the cleanest fossil fuel today is receiving tremendous rise in demand for both industrial and domestic energy requirements. The availability of natural gas requires it to be transported from the production ...
Techno-Economic, Environmental and Risk Analysis (TERA) for Power Generation -Market Growth

Mohamed, Wanis (Cranfield University, 2013-02)

Gas turbines (GTs) are extensively used in many power generation applications. This project has close coupled advanced, economic diagnostics with the technology of prime movers using a Genetic Algorithm (GA) to optimise the ...
Techno-environmental assessment of marine gas turbines for the propulsion of merchant ships

Bonet, Mathias Usman (Cranfield University, 2011-07)

This research study seeks to evaluate the techno-economic and environmental implications of a variety of aero-derivative marine gas turbine cycles that have been modelled for the propulsion of different types of merchant ...
Technoeconomic Environmental and Risk Analysis of Marine Gas Turbine Power Plants

Tsoudis, Evangelos (Cranfield University, 2008-07)

A novel generic Technoeconomic, Environmental and Risk Analysis (TERA) computational method was developed for marine power plants that are composed of existing or at preliminary design stage marine gas turbines. The ...
Technoeconomic evaluation of flared natural gas reduction and energy recovery using gas-to-wire scheme

Anosike, Nnamdi Benedict (Cranfield University, 2013-11)

Most mature oil reservoirs or fields tend to perform below expectations, owing to high level of associated gas production. This creates a sub-optimal performance of the oil production surface facilities; increasing oil ...
Technoeconomic evaluation of trigeneraton plant: Gas turbine performance, absorption cooling and district heating

Polyzakis, Apostolos (Cranfield University, 2006-11)

This PhD thesis is a demand led study taking into account changes in ambient conditions and power settings of a tri-generation power plant. Includes an evaluation tool for combined heat, cooling and power generation ...
Technoeconomic study of engine deterioration and compressor washing for military gas turbine engines

Varelis, Angelos G. (Cranfield University, 2008-09)

Despite spending much of their operating life in clear air, aircraft gas turbine engines are naturally prone to deterioration as they are generally not fitted with air filters. Engines are particularly at risk during ...
Technology catch-up actions for manufacturing companies in Pakistan

Iqbal, Numan (Cranfield University, 2004-08)

Technological development in manufacturing companies has been considered as a key contributor to the economic development of nations. Research has confirmed that the contribution of technological development to national ...
TERA for Rotating Equipment Selection

Khan, Raja S. R. (Cranfield University, 2012-01)

This thesis looks at creating a multidisciplinary simulation tool for rotating plant equipment selection, specifically gas turbines, for the liquefaction of natural gas (LNG). This is a collaborative project between Shell ...
Theoretical analysis and pressure distribution of thin-walled metal inverbuckle energy absorbing tubes

Chirwa, Efford Clive (Cranfield University, 1998-05)

This dissertation presents an investigation in the energy absorbing capacity of thin-walled metal inverbucktubes loaded in axial compression. It also presents the inversion-buckling(curling-buckling) behaviour achieved in ...
Theoretical and computation modelling of polymer seal life

Ho, Tsz Hang Emily Ting (Cranfield University, 1993)

Elastomer seals are widely used in the petroleum industry. Seal failure can be very expensive, due to losses in production and high maintenance costs. Another aspect of this problem is the difficulty in predicting the ...
Theoretical and experimental evaluations of the convective and conductive heat transfers in a domestic hot-water store

Chauvet, L. P. J. (Cranfield University, 1991-02)

The design of a water based thermal store for use in a domestic central heating system has been investigated theoretically, experimentally and numerically. The transient operation of the store during both the space ...
Theoretical and experimental studies of the Coriolis mass flowmeter

Sultan, G. (Cranfield University, 1990-03)

The Coriolis sass flowaeter is modelled using the theory of vibrating beams. Tube deformations for the fundamental mode and the next two nodes of natural (out-of-plane) vibration are worked out for many tube geometries. ...
