Contactless Inductive Flow Tomography (CIFT) is a flow measurement technique allowing for visualizing the global flow in electrically conducting fluids. The method is based on the precise measurement of very weak induced magnetic fields arising from the fluid motion under the influence of one or several primary excitation magnetic field(s).
At HZDR the technique is used to investigate laboratory experiments on turbulent Rayleigh-Bénard convection (RBC) phenomena as well as the industrial process of continuous casting (CC) of steel. In both cases the ternary liquid metal alloy Gallium-Indium-Tin is used as a model fluid. We will present latest experimental results on both topics, including a sophisticated flow analysis for RBC by means of Proper Orthogonal Decomposition (POD) and the first CIFT online process controller for CC.
Furthermore, we will give an outlook on the latest developments, namely the two-field excitation approach to increase the accuracy of the method.
