Rotating Rayleigh-Bénard Convection
Many flows in nature and technology are driven by buoyant convection and subsequently modulated by rotation. One of the classical convection systems is the Rayleigh-Bénard setup: a fluid in a container heated from below and cooled from above. An interesting variation of Rayleigh-Bénard convection is the case where the sample is rotated about the vertical axis. This system is relevant to numerous astro- and geophysical phenomena, including convection in the Arctic Ocean, in the earth's outer core, in the interior of gaseous giant planets, and the outer layer of the Sun. Thus the problem is of interest in a wide range of sciences, including geology, oceanography, climatology, and astrophysics. Furthermore, the knowledge can be used in industrial applications like metal production. We investigate turbulent rotating convection with experiments and numerical simulation.
