Revisiting Turbulent Convection

ORAL · Invited

Abstract

While asymptotic scaling of the heat transport has occupied considerable attention in turbulent Rayleigh-Benard convection over the years, we have learned much about this rich and complex flow along the way, through advances in experiments and numerical simulations. This includes the dynamics of a coherent mean wind in strongly turbulent flows in the presence of confinement and roughness, the response to time-dependent forcing, and the transition from weakly or non- rotating turbulent convection to rotation-dominated geostrophic convection in the limits of very high dimensionless rotation rates as well as large Rayleigh numbers, albeit close to their rotation-dependent critical values for convective onset. This talk will highlight recent work in these areas as well as some of the challenges for experiments and simulations.
