Recorded 27 January 2025. Rudie Kunnen of Eindhoven University of Technology presents "Confined rotating convection: a laboratory perspective" at IPAM's Rotating Turbulence: Interplay and Separability of Bulk and Boundary Dynamics Workshop. Abstract: Turbulent rotating Rayleigh-Bénard convection has been studied intensively. It is a simple, well-defined system that incorporates the interplay of buoyant forcing and rotation. Therefore, it is a decent 'first-order' model for many flows found in geophysics and astrophysics. While theoretical studies often assume a horizontally infinite layer of fluid, and numerical works can mimic that with periodic boundary conditions, in experiments there must be lateral confinement. From the pioneering experiments by Rossby (1969) it was already clear that the laterally confined system has different properties for onset of convection than the plane layer: Rossby saw that convection sets in below Chandrasekhar's (1953) result for the critical Rayleigh number. In the 1990's it became clear that a wavelike mode of convection, the 'wall mode', can form at the lateral walls while the bulk is still subcritical. The wall modes were expected to be washed away by bulk turbulence at larger Rayleigh numbers. However, in recent years it has become clear that the wall mode is a persistent and prominent feature of rapidly rotating turbulent convection. I will give a short history of investigations into the wall mode, discuss how it affects global heat transfer and overall flow structuring, as well as treat some recent ideas for suppression of the wall mode.
