Modeling and vibration analysis of a rocking–mass gyroscope system
(2008-04-01)
Rocking-mass gyroscope consists of an assembly of four cantilever beams with a rigid mass attached to them in the middle subjected to base rotations. Due to the gyroscope effect, the beams undergo coupled flexural-torsional ...
Optimization-based mechanism synthesis using multi-objective parallel asynchronous particle swarm optimization
(2008-12-01)
A distributed variant of multi-objective particle swarm optimization (MOPSO) called
multi-objective parallel asynchronous particle swarm optimization (MOPAPSO) is
presented, and the effects of distribution of objective ...
Design and analysis of the three degrees of freedom parallel kinematic machine
(2008-08-01)
The thesis is about design and analysis of a PKM with 3 DOF. The new PKM is designed as a machine tool in various applications in manufacturing. The PKM is optimized based on the developed stiffness model. Kinematics and ...
Evaporative drying of cupric-chloride droplets in a thermo-chemical cycle of hydrogen production
(2008-04-01)
This thesis develops analytical and numerical solutions that predict behavior of Cupric-Chloride droplets undergoing spraying and drying processes. Cupric-Chloride (CuCl2) is present as molten salt and slurry within the ...
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, ...
Process analysis and aspen plus simulation of nuclear-based hydrogen production with a copper-chlorine cycle
(2008-08-01)
Thermochemical processes for hydrogen production driven by nuclear energy are promising alternatives to existing technologies for large-scale commercial production of hydrogen, without dependence on fossil fuels. In the ...

(2008-12-01)
This study deals with the thermodynamic analysis of a molten carbonate fuel cell
(MCFC) hybrid system to determine its efficiencies, irreversibilities and performance.The analysis includes a performance investigation of ...
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 ...
