The objective of this research program has been to determine experimentally the extent to which horseshoe vortices modify turbulent convective heat transfer along a flat plate downstream of an appendage. The importance of appendage shape on the heat transfer behavior was evaluated by taking Stanton-number measurements downstream of both a cylindrical body and a streamlined body. The results indicate that a region of augmented heat transfer occurs near the centerline downstream of both obstacles, with Stanton numbers 10 to 50 percent over the undisturbed values. The streamlined cylinder produces the strongest modifications in heat transfer.
