A novel Internal Wave Generator for Oceanographic Application

We present a new kind of generator of internal waves. It allows to reproduce in a laboratory different internal waves encountered in real oceanographic situations. We will focus our presentation on three different profiles. (i) Internal tide beams as emitted by topographic features analogous to the Thomas and Stevenson self-similar solution of linear viscous internal waves. (ii) Mode-1 internal tide as generated by barotropic tidal flow past ocean bathymetry. (iii) Plane waves beams as generally assumed in theoretical derivations. Several experimental applications will be presented, at small and large scales, together with numerical simulations.
