The practical relevance of investigations of the effect of oscillations on convective heat transfer is discussed. Some experiments on overall heat transfer from a horizontal heated circular cylinder in a transverse, horizontal standing sound field are reported. Observations of local effects of sound on boundary layer thickness and heat transfer are described, and a correlation of heat transfer spanning all sound intensities is suggested in the light of these observations. The correlation is fitted well by the data, and thus provides adducive evidence for the explanation of the phenomena observed.
