The heat transfer relationships for shapes that approximate animal appendages have been experimentally determined. Finite length hollow cylinders, arcs, and cones with different amounts of closure were tested over a wide range of pitch and yaw angles at different wind speeds. The data for all of these shapes are within ±70 percent of the standard correlation for circular cylinders. Pitch and yaw variations have little effect on the heat transfer coefficient. Shorter length geometries and those with less enclosure have higher heat transfer than the longer and more enclosed geometries. The application of these results to modeling the heat transfer from animal appendages is illustrated.
