Abstract: The Contactless Inductive Flow Tomography is a procedure that enables the reconstruction of the global flow structure of an electrically conducting fluid by measuring the flow induced magnetic field outside the melt and subsequently solving the associated linear inverse problem. The accuracy of the reconstruction depends on the number and the distribution of the sensors around the vessel. The aim of this investigation is to find a sensor configuration for the reconstruction of a temperature driven flow of a liquid metal in a cylindrical vessel that employs as few sensors as possible without any significant loss of accuracy.
