Energy, exergy and cost analyses of nuclear-based hydrogen production via thermochemical water decomposition using a copper-chlorine (Cu-CI) cycle
(2008-04-01)
In this thesis the Copper-Chlorine (Cu-CI) thermochemical cycle and its components as well as operational and environmental conditions are defined, and a comprehensive thermodynamic analysis of a Cu-CI thermochemical cycle, ...
Effects of blade configuration on flow distribution and power output of a zephyr vertical axis wind turbine.
(2008-07-01)
Worldwide interest in renewable energy systems has increased dramatically, due to environmental concerns like climate change and other factors. Wind power is a major source of sustainable energy, and can be harvested using ...
Analysis of hydrodynamic phenomena in a fluidized bed for thermochemical hydrogen production
(2008-04-01)
This thesis examines transport phenomena of cupric chloride (CuCI2) hydrolysis within a fluidized bed. Conversions of CuCi2 and steam as a fluidizing gas are numerically investigated using a new non-catalytic gas-solid ...
Dynamic flowgraph methodology for reliability modelling of networked control systems: with application to a nuclear-based hydrogen production plant
(2009-12-01)
The use of communication networks in digital control systems introduces stability and reliability concerns. Standard reliability and safety assessment methods need further modification to accommodate the issue in the ...
Heat and fluid flow analysis in a molten CuCl heat exchanger
(2009-10-01)
The Cu-Cl thermochemical cycle is a promising method to generate hydrogen
as a clean fuel for human use in the future. The cycle can be coupled to nuclear
reactors to supply its heat requirements. The cycle generates ...
Multi-state system in a fault tree analsis of a nuclear based thermochemical hydrogen plant
(2008-07-01)
Nuclear-based hydrogen generation is a promising way to supply hydrogen for this large market in the future. This thesis focuses on one of the most promising methods, a thermochemical Cu-Cl cycle, which is currently under ...
Thermal performance analysis and geometrical optimization of automotive brake rotors.
(2008-07-01)
The heat dissipation and thermal performance of ventilated brake discs strongly depends on the aerodynamic characteristics of the air flow through the rotor passages. In this thesis, the thermal convection is analyzed using ...
Mass transport in the cathode electrode of a molten carbonate fuel cell
(2009-04-01)
A molten carbonate fuel cell (MCFC) is an electro-chemical energy conversion technology that runs on natural gas and employs a molten salt electrolyte. In order to keep the electrolyte in this state, the cell must be kept ...
Diffusion in inhomogenous media
(2009-10-30)
This project considers the diffusion of water molecules through a cellular medium
in which the cells are modeled by square compartments placed symmetrically in a
square domain. We assume the diffusion process is governed ...
