Resumo

Some experiments on a heated horizontal cylinder, 1.83 inches diameter, supported in a standing vertical sound field are described. Local measurements were obtained using a schlieren system. Results include local boundary layer thicknesses and temperature profiles. The experiments included frequencies of 709, 1084 and 1476 cps and sound pressure levels ranging from about 125 to 140 db. Large local effects were found at intensities below those at which the average heat transfer is altered significantly. An account is also given of observations at higher intensities, for which the flow does not remain steady.
