Direct numerical simulations of an inertial wave attractor in linear and nonlinear regimes

L Jouve, GI Ogilvie - Journal of Fluid Mechanics, 2014 - cambridge.org
In a uniformly rotating fluid, inertial waves propagate along rays that are inclined to the
rotation axis by an angle that depends on the wave frequency. In closed domains, multiple …
