Although heat transfer has been known to be capable of inducing acoustic phenomena [1], this investigation was initiated as a result of some observations made in recent heat transfer experiments. In studies of heat transfer to gaseous hydrogen and helium, McCarthy and Wolf [2] observed that the appearance of pressure oscillations in their apparatus caused heat transfer to become independent of Reynolds number. Hines and Wolf [3] reported the destruction of thin-walled test sections as a result of severe pressure oscillations accompanying heat transfer to supercritical hydrocarbons. Goldmann [4,5] has observed the production of acoustic noise, which he described as “heat transfer with a whistle” in forced convection heat transfer to two-phase and supercritical water. He has attributed this to large property variations under nonequilibrium conditions. Platt and Wood [6] reported flow oscillations and a means for eliminating them in the development of a liquid-oxygen heat exchanger. In view of this background, probing experiments were undertaken to establish the identity of such oscillations and to obtain some information of the conditions under which they occur.
