Design methodology and experimental verification used to optimize liquid overfeeding effects achieved with heat exchanger accumulators

Wood, Craig Willoughby 22 August 2012 (has links)
M.Ing. / This study involves the mathematical modeling and experimental verification of a heat exchanger accumulator. The study was initiated with a literature survey which, according to the author, revealed that there was no published material that described how heat exchanger accumulators are designed to ensure that they are correctly sized according to the operating system and conditions. The heat exchange process that takes place within the heat accumulator was studied and a mathematical model of a heat exchanger accumulator developed. This model was used to develop a universal design procedure that correctly sized the heat exchanger accumulator according to various requirements identified by the author. The model was then verified by conducting experimental tests and it was concluded that the model could be used to design heat exchanger accumulators.

Performance of a liquid flow ultra-compact heat exchanger

Sammataro, Michael A. 06 1900 (has links)
A numerical analysis of the performance of compact pin-fin array heat exchangers was carried out using water and JP-4 fuel as the working fluids. Three different configurations were used with hydraulic diameters ranging from 0.137 to 0.777 mm, and volumetric area densities varying between 4.5 and 14.5 mm2/mm3. Numerical simulations were carried out to determine the performance of each heat exchanger over a series of Reynolds numbers in both the laminar and turbulent flow regimes. It was found that very large heat transfer coefficients (in the kW/m2K range) can be achieved compared to air for the same footprint. In addition, the simulations were used to predict the Reynolds number range for transition from laminar to turbulent flow which was found to vary depending on the compactness of the heat exchanger configuration. As a final point, this study also investigated the effects of boiling of the liquid within the heat exchanger on its performance. It was found that despite improved heat transfer rates due to latent heat removal, vapor formation and resulting fluid expansion effects could result in undesirable flow patterns at low Reynolds numbers. The results from this study would be useful in the design of micro-scale heat exchangers for applications in the micro-electronic and gas turbine industries. / US Navy (USN) author.
