Experimental and theoretical investigations of a new integrated solar tower system for photocatalytic hydrogen and power production
(2013-08-01)
Solar energy conversion via photocatalytic hydrogen production from water is an attractive route for the propagation of a hydrogen economy. Increasing the efficiency of such systems to meet the target of 10% is essential ...
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 ...
Experimental investigation of scroll based organic Rankine systems
(2011-04-01)
In this thesis, an experimental research is conducted on scroll-based Organic Rankine Cycle (ORC) focusing on the expansion process. An important feature of the ORC is the ability to utilize low or moderate temperature ...
Energy ans exergy analysis of biomass co-firing in pulverized coal power generation
(2011-04-01)
Biomass co-firing with coal exhibits great potential for large scale utilization of biomass
energy in the near future. In the present work, energy and exergy analyses are carried out
for a co-firing based power generation ...
Energy, exergy and exergoeconomic analyses of gas-turbine based systems
(2011-12-01)
Gas turbines are the primary technology used for the purpose of power generation nearly everywhere. In this thesis, the Makkah Power Plant, running on a Brayton cycle, is considered for analysis. The peak demand for electric ...
Thermochemical energy storage systems: modelling, analysis and design
(2010-07-01)
Thermal energy storage (TES) is an advanced technology for storing thermal energy
that can mitigate environmental impacts and facilitate more efficient and clean energy
systems. Thermochemical TES is an emerging method ...
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 ...
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 ...
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 ...
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 ...
