Features of wave packeås propagation in two-layer fluid of finite depth

Applied hydromechanics, Vol. 7 (79) ¹ 1, (2005) p.80-89
Propagation of wave-packet at the interface of two layers of different properties is investigated with accounting of the surface tension. Using the method of multiple scale expansions the evolution equation is obtained in the third approximation. The structure of wave packats is analyzed and the comparison with analogous packats in the systems "half-space - half-space" and "layer - half-space" is carried out. The form of wave-packet and condition of the second harmonic resonance are investigated. The conditions of wave packet propagation of the ?-form and U-form are presented and the characteristic features of resonant region for the system "layer-layer" are found.
