The article is devoted to the study of the scattering of nonlinear acoustic waves on cylindrical bodies. There was made a review of publications on the scattering of acoustic waves by inhomogeneities of the medium in the form of cylindrical bodies and shells. There were noted features of the small parameter method application in nonlinear acoustics. A three-dimensional model of the geometry of the problem in cylindrical coordinates was presented, nonlinear wave processes occurring between the falling plane and scattered cylindrical waves were described. The inhomogeneous wave equation is solved by the method of successive approximations of series expansion in a small parameter. An asymptotic expression for the acoustic pressure of a difference-frequency wave was obtained. A program for calculating scattering diagrams has been developed, and an algorithm for its operation is given. The acoustic pressure scattering diagram of a differential frequency wave on a rigid cylinder and its three-dimensional model are presented. The radius of convergence of the used method of expansion in a small parameter is determined.

Although investigation of the linear scattering of acoustic waves by the elongated spheroid has been considered previously, results of the scattering of the nonlinearly interacting acoustic wave were not reported. In most previous publications, the problem is investigated when the angles of incidence of acoustic waves are θ = 0 0 and 90 0 [Kleshchyov & Sheiba, 1970], [Tetyuchin & Fedoryuk, 1989]. In article [Kleshchyov & Sheiba, 1970] the calculated diagrams of plane acoustic wave scattering by a similar size spheroid ( ξ 0 = 1,005 , kh0 = 10 ) at angle of incidence θ = 30 0 are presented. Also in this work the scattering diagram has maximums symmetrical to the angle of incidence (mirror lobes) with respect to z axis [Burke, 1966], [Boiko, 1983]. At angle of incidence θ = 0 0 forward scattering dominates. The basic maximum is aligned with 140 0 . When the angle of incidence is θ = 90 0 (lateral incidence), there are only two maximums – forward and backward. An analysis of the acoustic pressure distribution of the difference-frequency wave scattered field shows that the scattering diagrams have maximums in a backward direction. In direction to the angle of incidence, in lateral and transverse directions, plane waves have maximums. Incident high-frequency plane waves form the scattering field in backward and forward directions, and scattered spheroidal waves form the scattering field in transverse direction. An increase in the wave size of the spheroidal scatterer changes maximum levels, and an increase in the size of the interacting area around the elongated spheroidal scatterer leads to narrowing of these maximums. It is important to note that in this work we considered the case when the scattered field is generated by the secondary wave sources located in the volume around the spheroid. In the case of the linear scattering, these sources are located on the surface of the spheroid. The mirror maximums 30 0 and 150 0 appear as a result of the asymptotics of the first spatial sum (2 P−1 ) (ξ ,η , ϕ ) as confirmed in [2]. Therefore, the plotted scattering diagrams are in conformity with the results of 90 0 [Burke, 1966], [Kleshchyov & Sheiba, 1970], [Boiko, 1983], [Tetyuchin & Fedoryuk, 1989]. As for the numerical evaluation of the acoustic pressure, it is necessary to note the following. In view of the complexity of mathematical calculations, the obtained asymptotics allow for qualitative evaluation of the spatial distribution of the acoustic pressure in the scattered field. It would be more adequate to compare the results with experimental data. Unfortunately, experiments in non-linear conditions have not been carried out. For the sake of better understanding of contribution of the separated sums into the cumulative acoustic field, results were presented for two values of the wave dimension and the angle of incidence. It should be noted, that description of wave processes in spheroidal coordinates have several peculiarities. For example, comparing the acoustic pressure distribution at the distance from the scatterer, the results given in [Abbasov & Zagrai, 1994], [Abbasov & Zagrai, 1998], [Abbasov, 2007] can be taken. Spheroidal coordinates in a far field transform ( ( into spherical ones ( h 0 → 0) and P− 2 ) (ξ ,η , ϕ ) → P− 2 ) (r ,θ , ϕ ) . The results of this research are in agreement with results of prior studies of the scattering process described in spherical coordinates.
