Description
Description: Université de Lyon, Laboratoire de Physique de l'École Normale Supérieure de Lyon, CNRS, France. 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).
