Effects of oceanic ice cover and density stratification on the propagation of hydroacoustic waves
文献摘要：
The propagation characteristic of hydroacoustic waves is studied for an ideal compressible two-layer fluid with different densities covered by an elastic ice sheet. Boundary conditions are simplified by adopting linear assumption and then the dispersion relation is derived. The analysis and visualization of the dispersion relation present the introduction of compressibility leads to the appearance of hydroacoustic wave modes while the density stratification leads to the appearance of interfacial wave mode. Larger ice thickness and the density ratio of the two fluid layers increase the wave number and group speed of hydroacoustic waves at the same frequency while the phase speed decreases.
