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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 alkaline electrolyte based direct ammonia fuel cells
(2018-01-01)
In the present thesis study, alkaline electrolyte based direct ammonia fuel cells are developed, and their performances are evaluated through various parameters and efficiencies, such as open circuit voltages, polarization ...
