Onset of Küppers – Lortz-like dynamics in finite rotating thermal convection

  title={Onset of K{\"u}ppers – Lortz-like dynamics in finite rotating thermal convection},
  author={Angel Rubio and Juan M. L{\'o}pez and Francisco Marqu{\'e}s},
The onset of thermal convection in a finite rotating cylinder is investigated using direct numerical simulations of the Navier–Stokes equations with the Boussinesq approximation in a regime in which spatio-temporal complexity is observed directly after onset. The system is examined in the non-physical limit of zero centrifugal force as well as with an experimentally realizable centrifugal force, leading to two different paths to Küppers–Lortz-like spatio-temporal chaos. In the idealized case… CONTINUE READING
