Enhancing the effectiveness of Stirling engine regenerators
(2019-04-01)
A discrete heat transfer model is developed to determine which parameters influence the effectiveness of Stirling engine regenerators and quantify how they influence it. It is revealed that the regenerator thermal mass ...
Development and investigation of an ammonia synthesis reactor
(2018-08-01)
Ammonia production has gained increasing attention in the last decade due to its importance as a feedstock and an energy carrier. In the present thesis study, two novel ammonia production systems are presented. The first ...
Influence of sinusoidal motion on Stirling engines
(2018-12-01)
Stirling engines have a high potential to produce renewable energy due to their ability to use a wide range of sustainable heat sources and their high theoretical efficiencies. They have not yet achieved widespread use and ...
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 ...
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 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 ...
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 ...
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 ...
