Development and analysis of a high temperature electrolyser for the Cu-Cl cycle for hydrogen production
(2017-01-01)
A number of thermochemical cycles have been investigated to produce hydrogen from water. However, most of these cycles operate at over 800°C. The relatively lower temperature (550°C) requirement and use of inexpensive ...
Flow-sound interaction mechanism of a single finned cylinder in cross-flow
(2017-04-01)
The flow-sound interaction mechanism of a single finned cylinder in cross-flow is experimentally investigated and compared to that resulting from an equivalent bare cylinder. The flow field changes that result from the ...
Analysis of the thermal hydraulics of a multiphase oxygen production reactor in the Cu-Cl cycle
(2016-06-01)
In the thermochemical water splitting process by Cu-Cl cycle, oxygen gas is produced by an endothermic thermolysis process in a three-phase reactor. In this thesis, the required heat for the thermolysis process is provided ...
Investigation of sustainable hydrogen production from steam biomass gasification
(2010-12-01)
Hydrogen is a by-product of the gasification process and it is environmentally friendly with respect to pollution and emission issues when it is derived from a CO2-neutral resource such as biomass. It is an energy carrier ...
Experimental investigation and modeling of lithium-ion battery cells and packs for electric vehicles
(2016-01-01)
The greatest challenge in the production of future generation electric and hybrid vehicle (EV and HEV) technology is the control and management of operating temperatures and heat generation. Vehicle performance, reliability ...
Design, analysis and optimization of novel photo electrochemical hydrogen production systems
(2013-04-01)
Hydrogen is a green-energy carrier with a high heat of combustion. If obtained from renewable sources, it could be the ultimate and environmentally benign solution for the future energy requirements. This thesis presents ...
Investigation of new phase change material based thermal management systems for Li-ion batteries
(2017-01-01)
In this thesis, a battery pack consisting of three A123 20Ah cells connected in series is tested with various cooling methods at different discharge rates. Four different coolant inlet temperatures are selected for the ...
Development of polymer based nanocomposite using electrospinning for sound absorption and isolation
(2017-01-01)
Excessive noise has adverse effects on human health. Therefore, it is necessary to find innovative methods for decreasing the exposure to noise in the environment. Various materials are used for dampening noise. In order ...
A temporal topic model for social trend prediction
(2017-08-01)
Social media provides increasing opportunities for users to voluntarily share their thoughts and concerns in a large volume of data. While user-generated data from each individual may not provide considerable information, ...
Design, analysis and experimental investigation of Cu-Cl based integrated systems
(2013-01-01)
Burning fossil fuels for power generation results in emissions of greenhouse gases such as carbon dioxide (CO2) and air pollutants such as nitrogen oxides (NOx) and sulfur oxides (SOx), which are harmful to living creatures ...
