On Dispersion Relation for Gravity Waves in the Presence of Condensate
Abstract
During direct numerical simulation of isotropic turbulence of surface gravity waves in the framework of Hamiltonian equations the formation of long wave condensate was observed. Here we study the influence of the condensate presence on the dispersion relation for the gravity waves. Formation of the two side bands, corresponding to the interaction with condensate, was observed. Distortion of the dispersion relation can be a factor influencing the spectra of inverse and direct turbulent cascades.
