Measurement of torsional and sloshing modes in Rayleigh-Bénard convection using contactless inductive flow tomography

Flows driven by temperature differences play an important role in geo- and astrophysics as well as in many metallurgical applications. The dynamics of the large scale circulation (LSC) of Rayleigh-Bénard (RB) convection include azimuthal reorientations, cessations, torsional and sloshing modes. In this presentation we will show that the contactless inductive flow tomography (CIFT) is able to visualise these features. This will be shown using numerical simulations as well as measurements at a small model filled with GaInSn.
