Further Results on Nonlinear Energy Transfer in Gravity-Capillary Wave Spectra, with Viscous Considerations,
Abstract
Further studies have been made on the effect of viscosity and on the spectral-shape dependence on the energy flux of a gravity-capillary spectrum. Viscous effects have been included as a perturbation of the inviscid results and also in a more exact manner, producing an effective decoupling of gravity and capillary waves, suggesting that the growth of gravity-capillary waves in the front face of the spectrum must be mostly dependent on the energy flux from the wind. However, at an early stage of development, the nonlinear resonant interactions may still play a significant contribution to the growth of the gravity-capillary wave spectrum. The investigation is concluded with a brief description on the effect of nonlinear resonant interactions and surface tension to the second-order contributions to the doppler spectrum of radio waves backscattered from a water-wave system.
