Ivanov V.V., Labutin S.A., Mel'nikov V.I. «Computer acoustic diagnostic system for two-phase flows» Приборы и техника эксперимента, 36, № 1, с. 238-239 (1993)

The authors describe a system determining the local and volume steam content, the velocity of the motion and the size of steam or gas bubbles in a liquid flow. The complex includes four acoustic converters, a measuring part connected with a computer and made in the form of a plate located inside the computer and a package of applied programmes. The measurement of the parameters of two-phase flows is based on the measurement of a signal passing from a radiator of an acoustic pulse to an acoustic receiver. The main technical characteristics are given.

The apparatus permits to measure the electromagnetic (EMR) and acoustic (AR) radiations during uninterrupted prolonged measurements when simulating the processes of fractures for rock samples. It ensures the EMR and AR energy spectra determination and their combined processing in such main parameters as signal energy and number of signal, mean signal energy and energy release. The apparatus allows to obtain a new prognostic parameter of rock fracture, determined as the ratio of total energies of EMR and AR.

A brief analysis is given for the results of physical description of the method; its potentialities and conditions of implementation for probing the distribution of bulk charge’s electric field intensity and polarization across a plane-parallel sample are considered. A device implementing the method on the basis of the inverse piezoelectric effect is described. This device makes it possible to probe the samples with frequencies of hundreds and thousands Hz with a field sensitivity threshold ≤10² v/cm and a resolution ≤20 μm. The application of the method is illustrated by experimental results.

Using the external proton beam of the accelerator at the Institute of Theoretical and Experimental Physics (ITEP), an experiment was performed on recording the acoustic signals accompanying the moderation (up to termination) of an intense proton beam with an energy of up to 200 MeV in water. The signals are damped quasi-periodic oscillations, whose initial period reflects the features of the radiating system. Parameters of the acoustic signal are measured in a wide range of energy release (from 10¹⁶ to 1.2·10¹⁹ eV) for three values of the beam diameter.
