| Abstract: | The paper analyzes the mixing features in numerically generated shear waves by simulating the circulation during SANDYDUCK experiments. Different wave resolving Boussinesq type models and a wave averaged model have been compared. They produce different velocity/vorticity fields and in turn different mixing properties. Lagrangian statistics have been used to study this aspect. Differences in absolute and relative dispersion and diffusion have been pointed out. All the models seem to follow a Richardson-like intermediate regime for the longshore relative dispersion even though some results seem to suggest a dependency from particles separation weaker than the classical 4/3 law. | |
