Studies of Heat Transfer in Complex Internal Flows.
Abstract
This is the final report of a research program whose objective was to determine the heat transfer and pressure drop characteristics of heat exchange devices subject to highly complex fluid flows. The report consists of two parts. The first part summarizes the results of research that has already been described in progress reports, while the second part conveys the results of investigations conducted and completed since the distribution of the last progress report. The general theme which runs through the work is a search for the effects of flow maldistribution on heat transfer in various types of heat exchange devices. The maldistribution may be caused by the turning of the flow upstream of the inlet, abrupt changes of cross-sectional area, blockage, competition between parallel flow passages, misalignment of the inlet and outlet of plenum chambers, swirl, and the presence of enhancement devices. The investigated geometries included tube banks in crossflow, circular tubes, and rectangular flow passages.
