ENERGY SPECTRA OF ENSEMBLE OF NONLINEAR CAPILLARY WAVES ON A FLUID

Energy Spectra of Ensemble of Nonlinear Capillary Waves on a Fluid

The problem of spectral description of the nonlinear capillary waves on the fluid surface is discussed.Usually, three-wave nonlinear interactions are considered as a major factor determined by the energy spectrum of these waves in the kinetic wave turbulent regime.We demonstrate that four-wave interactions should be taken into account.In this case,
