Liu Yan, Liu Shi, Lei Jing, Liu Jing, Schlaberg H.Inaki, Yan Yong «A method for simultaneous reconstruction of temperature and concentration distribution in gas mixtures based on acoustic tomography» Акустический журнал, 61, № 5, с. pp597-605 (2015)

The acquisition of the concentration and temperature distributions in a mixed gas system plays a crucial role in real industrial applications. Different from comment measurement method, in this paper an acoustic tomography (AT) based method is developed for the simultaneous reconstruction of the concentration and temperature distributions. The proposed method includes two stages. In the first stage, the correlations of the acoustic velocity and the intensity attenuation with the temperature and concentration are investigated. Then the approach that can simultaneously compute temperature and concentration is proposed. In the second stage, in order to achieve 2D tomography, the stochastic inversion method for solving the inverse problem is developed. Numerical simulations are implemented to validate the feasibility of the proposed reconstruction method.

Hongkun Zhou, Lianjin Hong «Long waves induced motions to rigid spheroids» Акустический журнал, 61, № 3, с. pp287-292 (2015)

Responses of unconstrained and rigid spheroidal bodies subjected to long sound waves are analyzed by means of approaching hydrodynamic method. It is shown that in the low-frequency approximation the amplitude of translational velocity is completely determined by the density as well as the acoustic added mass which is equal to hydrodynamic one associated with the body. The inconformity of responses to sound waves in virtue of geometric asymmetry is also presented. In addition, rotational movement engendered by acoustic oblique incidence is discussed, and it represents as the modulated angular oscillation similar to the beat-frequency vibration. All these analyses on acoustically induced motions provide a theoretical evidence for developing spheroidal inertial vector receivers.
