Acoustics of hole liquid with presence of weak chemical reaction in gas

The behaviour investigation of single spherical holes in hariable fields of pressure is the aim of the paper as well as the linear theory development of the sound wave propagation in the hole liquid with the presence of chemically active admixtures in gas. During the investigation the analytical solution of the heat conduction problem in the gas phase by the Fourier method for the case of linear oscillations of a gas hole has bee used as well as the asymptotical analysis of the interphase thermal flow on the thickness of a temperature boundary layer in gas in the acoustics problem. As a result the method of the interphase heat exchange description with the help of Duhamel integral with a root nucleus has been suggested and substantiated. The dependence of a damping parameter of gas hole radial oscillations on thermal physical and chemical properties of gas has been obtained. The linear theory of the long sound wave propagation in the hole liquid with the presence of a dissociating component in gas has been constructed. The investigation results may be used in the numerical calculation of applied problems of acoustics for the hole liquid with chemically active admixtures in the gas phase. The paper results may find their field of application in the linear theory of the weak disturbance propagation in liquid with gas holes; in the amplification modelling of the sound wave damping by dissociating admixtures in the gas phaseAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
