| Zusammenfassung |
| Internal wave attractors have been observed in relatively simple domains and with linear stratifications. A natural question is whether attractors persist when the domain boundary or stratification is perturbed. We present laboratory experiments where the domain boundary is perturbed with a variety of side walls. Although scattering of the internal wave beams takes place, we find that the energy remains closely linked to the presence of the unperturbed attractor. Also a non-uniform stratification does not lead to disappearance of the attractor. These findings indicate that the attractor is stable under perturbations of domain and medium. |
