In this experiment a kind of mixed-convection heat transfer of a horizontal circular cylinder in a vertical rectangular conduit is examined, by using a straight acoustic streaming by an audio-speaker as an aiding flow, and the results are compared with the ones for a fan. As a result, it is revealed that the augmentation mechanism of heat transfer of a cylinder by acoustic streaming is the same as that by a fan. i. e. it is due to the increase of the aiding flow speed of the forced convection. It is also revealed that the frequency dependence of the augmentation is the same as that of the flow speed of the acoustic streaming, and that the intermittent flow characteristics of the acoustic streaming are somewhat important for the augmentation.
