Large-scale vertical vorticity generated by two crossing surface waves

Two crossed surface waves generate vertical vorticity in a viscous fluid due to hydrodynamic nonlinearity. We find parameters of the induced flow and investigate its excitation and damping dynamics, focussing on the case of large-scale vorticity (in comparison with the wavelength), corresponding to surface waves crossing at a small angle. We also show that a thin insoluble liquid film (possibly covering the fluid surface due to contamination) increases the induced flow intensity not only at the surface, but also in the fluid bulk. We discuss our results in view of recent experimental observations of large-scale vortex flows.
