Avramenko O. Hydrodynamic wave propagation in systems of non-homogeneous structure

The object of investigation is the wave processes in non-homogeneous systems. The subject of investigation is hydrodynamic and hydroelastic waves in the systems of inhomogeneous structure. The methods of investigation are the methods of multiple scale expansions and of integral transformations. Scientific news: higher approximations of new non-linear hydrodynamic problems of wave packets propagation in two-fluids systems have been obtained; the wide class of generation, propagation and transformation problems for internal and surface waves and new hydroelastic problems of the acoustic wave propagation in the layer systems and the pulse wave in cylindrical systems was solved. Sphere of use is oceanology, biomechanics, machine- and shipbuilding, hydroacoustics. The results were realized in sctientific works of IHM NASU and at international project INTAS.
