Surface waves on currents with arbitrary vertical shear

Surface gravity waves in deep fluid at vertical shear flows

Special features of surface gravity waves in deep fluid flow with constant vertical shear of velocity is studied. It is found that the mean flow velocity shear leads to non-trivial modification of surface gravity wave modes dispersive characteristics. Moreover, the shear induces generation of surface gravity waves by internal vortex mode perturbations. The performed analytical and numerical stu...

Surface Waves on Veritcally Sheared Currents

A new perturbation analysis is presented which provides a first approximation to the wave-current interaction. The model is shown to provide a good description of laboratory data provided by Swan, Cummins & James (2000) and of results from a numerical formulation. These comparisons confirm that the near-surface vorticity leads to an important modification of the dispersion relation. The results...
