“…Acoustic methods may also be useful for monitoring closed thermohydraulic loops and other pressurized systems, such as reactors in which sonic and ultrasonic noises are generated. The Argonne National Laboratory conducted research and development of acoustic surveillance of reactor and power plants to develop an understanding of the sources of unusual sound, and a performance analysis was conducted to show that a combined acoustic neutronic system was feasible and that such a system would provide a rapid means of reactor shutdown [1,2]. Acoustic emission induced by boiling and cavitating bubbles in ideal and viscous liquids had been studied by a number of authors [3][4][5][6][7][8].…”

Abstract:The problem of high-frequency acoustic emission generated by a spherical hot liquid drop in a cool ambient liquid (water) is considered analytically. It is assumed that the acoustic emission is generated by the motion of the vapor cold liquid interface, which is described by the Rayleigh equation for a spherical bubble. It is also assumed that the linear relationship between the saturated pressure and the temperature is governed by the Clapeyron-Clausius law, that heat transfer from the hot liquid drop to the vapor film and the liquid takes place by a radiation, and that heat transfer from the water-vapor interface to the ambient liquid takes place by conduction. Solution of the equation obtained gives an approximate radius time relationship that allows us to evaluate the kinetic enthalpy and acoustic pressure in a far field. It is shown that, in the first approximation, the spectral density of the acoustic energy emitted by such a phenomenon varies as the minus 2.7 power of the frequency and decreases by approximately 8.1 decibels per octave with a rise in frequency.
