Abstract

This paper describes an experimental investigation of convective heat transfer over the back ofan inclined rectangular plate in cross flow. From time-averaged data, the local heat transfer distribution is shown to be very sensitive to plate orientation but almost independent ofv elocity in the range studied. Time-resolved data exhibit very strong heat transfer fluctuations generally, with slight evidence of periodicity associated with vortex shedding in the wake. However, the heat transfer fluctuations in the wake are mainly characteristic of random, small scale turbulence, as reported previously for a cylinder in cross flow.
