Development and analysis of a solar-based integrated system with a CO2 Rankine power cycle
(2013-10-01)
The current work is a thermodynamic-based design and analysis of a solar-based
integrated system for power production. In this regards, a reheat supercritical carbon
dioxide (S-CO2) Rankine cycle is proposed. This cycle ...
Development and investigation of compressed air only and hybrid powering options
(2016-04-01)
Currently, significant resources are deployed to investigate electric and pneumatic vehicles in response to environmental, energy and consumer pressures. The goal of this thesis is to show conceptual development, analyze, ...
Development of waste management systems: applications of Durham Region
(2021-08-01)
This thesis aims to reduce environmental impacts and increase overall efficiencies of domestic waste management systems by proposing case studies for Durham Region. Case study 1 integrates an anaerobic digestion facility ...
Experimental investigation and analysis of a new light-based hydrogen production system
(2014-12-01)
Due to the world’s increasing population and the rising standard of living, global energy demand is expected to keep increasing. The limited nature of fossil fuels and their non-homogenous global distribution along with ...
Investigation of drying conditions for dental practice loads
(2019-04-01)
This thesis investigates different drying techniques for dental practice loads experimentally and numerically. Several experiments are carried out by changing both top and bottom wall temperatures while changing the ranges ...
Investigation of mechanical heat pump systems for heat upgrading applications
(2016-04-01)
Three high temperature heat pump systems based on vapor compression cycles are introduced and examined. Four fluids (water, cyclohexane, biphenyl and mercury) are selected and analysed thermodynamically as prospective ...
Thermodynamic anaysis of an integrated photovoltaic system for hydrogen and methanol production
(2012-06-01)
A solar based integrated system for hydrogen and methanol production is investigated. Energy and exergy analyses of a hydrogen production plant, thermodynamic assessment of methanol synthesis plant, and exergy analysis of ...
Exergoeconomic analysis and optimization of organic Rankine cycles
(2012-03-01)
Heat sources such as biomass, industrial waste heat and solar thermal provide the
potential to produce renewable environmentally low impact electricity. Using these
resources efficiently within economic constraints is ...
Thermodynamic performance assessment of three biomass-based hydrogen production systems
(2010-04-01)
Hydrogen is likely to be an important energy carrier in the future. It can be produced by the steam reforming of natural gas, coal gasification and water electrolysis among other processes. However current processes are ...
Development of novel energy systems for LNG locomotives
(2015-04-01)
The use of diesel in the railway sector brings challenges to the engineers to meet the current emissions standards set by governments. This thesis addresses potential solutions to overcome the emissions problems in the ...
