Abstract

The objective of this study was to develop and present a correlation equation for the representative or 'average' heat transfer coefficient associated with horizontally oriented circular pin fins that accounts for the effect of both modes of heat transfer, convection and radiation. Four aluminum test pins of circular cross-section with diameters of 3.18, 6.35, 9.53, and 12.7 mm were used to develop the correlation equation. This correlation is supplied to students in the undergraduate heat transfer laboratory for use in the design of a fin attachment using the design-build-test approach. In the experiment, student teams design, build, and test a fin attachment to increase the heat loss from a surface.
