Mode interaction in rotating Rayleigh-Benard convection

Fluid Dyn. Research. 33 (2003) 477-492.


The results of direct numerical simulations of convection in a uniformly rotating vertical cylinder with no-slip boundary conditions are described, and used to study the dynamics associated with transitions between states with adjacent azimuthal wave numbers far from onset. In certain regimes a novel burst-like state is identified and described. A dynamical-systems explanation for this behavior is suggested.
