| Nonlinear stability of wave packets propagating along the interface between the two fluid layers of different densities with taking into account the surface tension is investigated. The analysis is carried out by the method of multiple scale expansions up to the third order approximation. Characteristic diagrams of nonlinear stability at different thicknesses of the lower layer are presented. The essential redistribution of nonlinear stability regions with changing fluid layer thickness ratio is discovered. |
