Heat transfer in an oscillating flow at high acoustic Reynolds number has been investigated using the mass-transfer analogy. Subliming naphthalene has been used in the experiments. In these experiments the acoustic Reynolds number was varied over a range from well below the values where acoustically generated turbulence is expected to occur to values above the anticipated transition value. A mass transfer (or heat transfer) rate increasing with Reynolds number, as would be expected with a turbulent flow, is observed, but beginning at Reynolds numbers an order of magnitude below the expected turbulent transition values and continuing with the same form to values well above the transition Reynolds number.
