Application Of A High-Performance Optically Enhanced Solar Thermal Collector System, Timothy H. Cameron
Application Of A High-Performance Optically Enhanced Solar Thermal Collector System, Timothy H. Cameron
Honors Theses
In an effort to make Union College a more environmentally friendly campus, this research project focuses on the application of Union’s liquid-based solar thermal collector system. The motivation for this research project is due to the increasing demand for renewable energy sources in order to decrease our society’s dependence on fossil fuels. The system features nine, 16-tube, evacuated tube solar modules which absorb radiant solar energy from the sun. Through a two loop system, thermal energy is stored in water within two-80 gallon storage tanks. This research project involves the design, construction, and analysis of two applications in order to …

Wayne State University Dissertations
Sonic Infrared (IR) Imaging Nondestructive Evaluation (NDE) technology has shown inherent advantages, such as fast detection for all direction and all dimension flaws, for both metal and composite materials. The purpose of this dissertation is to study and investigate the physical process of two most important methods, frequency sweep excitation and chaotic excitation, to improve the defect detection ability of Sonic IR technology.
The tool used in our study is known as finite element analysis (FEA). According to test process of Sonic IR technology, some special technologies were developed in FEA simulation, such as creating cracks with flat contact surfaces …
