New developments in Contactless Inductivee Flow Tomography

The contactless inductive flow tomography (CIFT) is a measurement technique that allows for reconstructing the mean global flow of an electrically conducting fluid. This is done by applying a primary magnetic field, measuring the flow induced secondary field outside of the container and solving the underlying inverse problem. A promising candidate for the application of CIFT is the continuous casting of steel, where any means of online flow-monitoring could help improving the process and might as well give new insights to the processes in the casting mould. In this paper we will give an overview of the achievements in tailoring CIFT to models of continuous casting, being in particular (a) a two-phase flow in a slab-mould using Argon injection, (b) a mould with an electromagnetic stirrer around the submerged entry nozzle, and (c) the application to a mould influenced by a strong electromagnetic brake (talk only).
