Research on Nonlinear Steady-state Resonant Acoustic-gravity Waves
The propagation speed of acoustic-gravity waves in seawater is close to the speed of sound,which is ten times faster than the speed of tsunamis.In previous studies of resonant acoustic-gravity waves,only the linear terms in the governing equation were considered.In the paper,based on the homotopy analysis method,a completely nonlinear governing equation for the acoustic-gravity wave is solved to obtain the resonant acoustic gravity wave system in equilibrium under precise resonance conditions.We also verified the rationality of using the linear governing equation to solve the acoustic-gravity wave problem.
