| Abstract: | The sound accompanying nucleate and film boiling on a platinum wire immersed in a water pool at atmosphere pressure is related to the rate of heat transfer from the wire surface. In particular the total sound intensity is shown to be a function of the heat transfer resulting from bubble evolution. Analysis of the acoustic spectra for saturated and sub-cooled boiling shows how the level of selected components varies with changes in the heat flux and liquid temperature. The possibility of using an acoustic detection device to detect boiling caused by channel blockage in a liquid cooled system is discussed. |
