Abstract Details

2009, Master of Science (MS), Ohio University, Mechanical Engineering (Engineering and Technology).
The purpose of this work was to use copper micro-channel tube to design, construct and analyze the performance of a loop thermosyphon prototype. The design stage included a pressure loss analysis to ensure working fluid circulation. Analytical, numerical and experimental analyses were performed to calculate the heat transfer coefficient and heat transfer and to compare the results. The analytical analyses consisted of estimations of the heat transfer coefficient and heat transfer with the fin theory, and flow over a flat surface. The numerical analysis was performed using the computational fluid dynamics software Fluent. The experimental work was conducted on a small-scale wind tunnel under constant air flow, 0.5 and 1.0 m/s, and different operating temperatures, ~50°C and ~70°C. Propane was chosen as the working fluid for the system due to its relatively low global warming potential, saturation temperature range, availability, ease of storage, and non toxic properties. This work confirmed the concept of a loop thermosyphon by providing an isothermal surface throughout the prototype. The isothermal fins increased the heat transfer by a maximum of 63% compared to the classical fin mode.
