AbstractWe consider strongly nonlinear waves in fluids in a uniform gravity field, and demonstrate that an incompressible wave motion, in which pressure remains constant in each fluid parcel, is supported by compressible fluids with free and rigid boundaries. We present exact analytic solutions of nonlinear hydrodynamics equations which describe the incompressible wave motion. The solutions provide an extension of the Gerstner wave in an incompressible fluid with a free boundary to waves in compressible three-dimensionally inhomogeneous moving fluids such as oceans and planetary atmospheres.

Nonlinear Hydrodynamics

Alpha decay is described as a new large amplitude collective motion in nuclei. The total energy is evaluated in the frame of the nonlinear hydrodynamics approach which leads to the formation of solitons on the nuclear surface. A new minimum appears in the total energy due to the shell effects for 208 Pb and 4 He introduced phenomenologically. The minimum was chosen to be degenerate with the ground state minimum. Consequently a new coexistence model consisting of the usual shell model and an alpha particle cluster-like model describing a soliton moving on the nuclear surface is obtained. The corresponding amplitudes describe excellently the experimental preformation factors for alpha decay of Po isotopes.
