Performance investigation of various cold thermal energy storages
(2008-07-01)
This study deals with solidification and melting of some typical encapsulated ice thermal energy storage geometries. Using ANSYS GAMBIT and FLUENT 6.0 software, HTF fluid motion past encapsulated water (ice) geometries, ...
Investigation of a hydrogen production process through aluminum and water chemical reaction
(2019-12-01)
This thesis reported a novel hydrogen production experimental set up, which utilized the chemical reaction between aluminum and water to produce hydrogen. The constructed experimental setup had an aluminum powder spraying ...
Thermodynamic performance evaluation and experimental study of a Marnoch Heat Engine
(2009-10-01)
The Marnoch Heat Engine (MHE) is a recently patented type of new heat engine that
produces electricity from lower temperature heat sources. The MHE utilizes lower
temperature differences to generate electricity than any ...
Thermodynamic anaysis of an integrated photovoltaic system for hydrogen and methanol production

(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, ...
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 ...
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 ...
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 ...
