experimental determination of shell side heat transfer coefficient and pressure drop for an Oil Cooler shell and tube heat exchanger with three different tube bundles
Applied Thermal Engineering, 2007Co-Authors: Reza Hosseini, A Hosseinighaffar, M SoltaniAbstract:In this paper, the heat transfer coefficient and pressure drop on the shell side of a shell-and-tube heat exchanger have been experimentally obtained for three different types of copper tubes (smooth, corrugated and with micro-fins). Also, experimental data has been compared with theoretical data available. Correlations have been suggested for both pressure drop and Nusselt number for the three tube types. A shell-and-tube heat exchanger of an Oil Cooler used in a power transformer has been modeled and built for this experimental work in order to investigate the effect of surface configuration on the shell side heat transfer as well as the pressure drop of the three types of tube bundles. The bundles with the same geometry, configuration, number of baffles and length, but with different external tube surfaces inside the same shell were used for the experiment. Corrugated and micro-fin tubes have shown degradation of performance at a Reynolds number below a certain value (Re < 400). At a higher Reynolds number the performance of the heat exchanger greatly improved for micro-finned tubes.

thermal hydraulic performance of a novel shell and tube Oil Cooler with multi fields synergy analysis
International Journal of Heat and Mass Transfer, 2014Co-Authors: Jie Yang, Jiaju Liu, Wei LiuAbstract:In the present paper, a novel shell-and-tube heat exchanger is proposed for the application of Oil Cooler. It is numerically investigated compared to a rod baffles shell-and-tube heat exchanger using the commercial software FLUENT 6.3 and GAMBIT 2.3. The results of heat transfer, flow characteristics, and comprehensive performance are analyzed for both tube-side and shell-side with verifications of correlations and experimental apparatus. For tube-side, the novel heat exchanger demonstrates evidently excellent overall performance; while for shell-side, the novel heat exchanger illustrates slightly lower comprehensive performance than the rod baffles one. The path lines, pressure field, and temperature field are analyzed and the multi-fields synergy principle is adopted to evaluate the synergy extent between velocity, temperature, and pressure fields.
