Abstract

Numerical works are conducted to develop a visualization technique for the phase distribution in a two-phase flow field with electrical impedance tomography (EIT) technique, which reconstructs the resistivity distribution with the electrical responses that are determined by corresponding excitations. Especially, this study applies the EIT to the imaging of two-phase flow fields where complex internal structures like rod bundles are engaged. For the improvement of the image reconstruction performance, the information on the internal structures is incorporated in the inverse algorithm and the use of the internal structures as the internal electrodes is proposed. With an enhanced EIT algorithm, this study attempts to reconstruct the images of the simulated bubble distributions and the reconstructed images imply the potential possibility of the electrical impedance tomography for the visualization of two-phase flow through complex structures like rod bundles.
