Gap solitary waves in two-layer fluids

We present computations of solitary waves in a two-layered fluid flow. Both the effects of gravity and interfacial tension are considered. The top surface of the upper fluid is free. The solitary waves are found in a narrow 'gap' which exists between the two branches of the dispersion rela...

Description
Summary:	We present computations of solitary waves in a two-layered fluid flow. Both the effects of gravity and interfacial tension are considered. The top surface of the upper fluid is free. The solitary waves are found in a narrow 'gap' which exists between the two branches of the dispersion relation. Both in-phase and out-of-phase solitary waves are presented.
