| Zusammenfassung |
We revisit experimental studies performed by Ekman on
dead-water (Ekman, 1904) using modern techniques in order to present
new insights on this peculiar phenomenon. We extend its description to more
general situations such as a three-layer fluid or a linearly stratified fluid
in presence of a pycnocline, showing the robustness of dead-water phenomenon.
We observe large amplitude nonlinear internal waves which are coupled to the
boat dynamics, and we emphasize that the modeling of the wave-induced drag
requires more analysis, taking into account nonlinear effects.
Dedicated to Fridtjöf Nansen born 150 yr ago (10 October 1861). |
