Applying the contactless inductive flow tomography to a model of continuous steel casting

We utilize the contactless inductive flow tomography (CIFT) for visualizing the flow of GaInSn in a model of continuous steel casting. Since for thin slab casting the velocity can be assumed to be mainly two-dimensional it is sufficient to apply only one external magnetic field and to measure the induced fields at the narrow faces of the mould. In a first step we show that a numerically determined flow field can be reconstructed by CIFT with an empirical correlation coefficient of about 75 per cent. Then we apply the method to various single-phase and two-phase flows in the real model and show that typical flow features can be reliably detected.
