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 ...
Optimization of plastic scintillator thicknesses for online beta detection in mixed fields
(2010-12-01)
For efficient beta detection in a mixed beta gamma field, Monte Carlo simulation models have been built to optimize the thickness of a plastic scintillator, used in whole body monitor. The simulation has been performed ...
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 ...
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 ...
Monte Carlo simulations for the purpose of efficiency curve calibration for the Fastscan whole body counter
(2015-08-01)
In order to be able to qualify and quantify radiation exposure in terms of dose, a Fastscan whole body counter must be calibrated correctly. Current calibration methods do not take the full range of body types into ...
Development of thermodynamic cycles for sodium-cooled-fast reactors.
(2013-12-01)
Currently, one engineering challenge is designing Generation IV (GEN-IV) Nuclear Power Plants (NPPs) with significantly higher thermal efficiencies compared to current NPPs, and to match, or at least to be close to, the ...
Energy and exergy analyses of biomass cogeneration systems
(2012-08-01)
Biomass cogeneration systems can generate power and process heat simultaneously from
a single energy resource efficiently. In this thesis, three biomass cogeneration systems are
examined. Parametric analysis of back pressure ...
Analysis and optimization of fuel cell based integrated powering systems for clean rail applications
(2019-08-01)
In this thesis, proposals of novel integrated fuel cell powering systems for cleaner railway applications are presented and analyzed thermodynamically. Both energy and exergy analyses are conducted on these systems for ...
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 ...
Modeling, analysis and optimization of integrated energy systems for multigeneration purposes
(2013-08-01)
Energy use is directly linked to well-being and prosperity across the world. Meeting the growing demand for energy in a safe and environmentally responsible manner is an important challenge. There are around seven billion ...
