Vortex cluster arising from an axisymmetric inertial wave attractor
We present an experimental and numerical study of the nonlinear dynamics of an inertial
wave attractor in an axisymmetric geometrical setting. The rotating ring-shaped fluid domain …

Rapidly rotating precessing cylinder flows: forced triadic resonances
Rapidly rotating cylinder flows subjected to low-amplitude precessional forcing are studied
numerically over a range of cylinder and precessional rotation rates. For sufficiently small …

Zonal flow in a resonant precessing cylinder
A cylinder undergoes precession when it rotates around its axis and this axis itself rotates
around another axis. In a precessing cylinder full of fluid, a steady and axisymmetric …

Nonlinear and detuning effects of the nutation angle in precessionally forced rotating cylinder flow
The flow in a rapidly rotating cylinder forced to precess through a nutation angle α is
investigated numerically, kee** all parameters constant except α, and tuned to a triadic …
