Abstract
Contactless Inductive Flow Tomography is able to reconstruct the three-dimensional flow field in conducting liquids by measuring the flow induced deformation of an applied magnetic field outside the liquid and by solving subsequently a linear inverse problem. In this paper, we will present a design of the arrangement of excitation coils and magnetic field sensors for a new Rayleigh-Bénard cylindrical convection cell with a diameter of 320 mm and a height of 640 mm filled with the eutectic alloy GaInSn. Based on this new setup first reconstructions will be shown. Figs 4, Refs 12.
