Abstract
Electrical impedance tomography (EIT) is widely studied when dealing with multiphase flow. This method presents a technical advantage over others, as it is a non-intrusive and radiation-free technique. It allows to quantify specific flow patterns, flow measurements, along with others applications. Basically, it consists of setting electrodes in the limits of a body and obtain electrical measurements such as voltage and impedance, these measurements together with mathematical models allow to reconstruct an image of the interior. This image is calculated by the algorithms of inverse problems, such as Gauss-Newton minimization regularized by the Tikhonov technique, this combination allows to estimate the distribution of conductivity within the domain and thus indirectly the distribution of the multiphase fluid. In this work, the software Electrical Impedance Tomography and Diffuse Optical Tomography Reconstruction Software (EIDORS) together with a developed low-cost EIT system is used to reconstruct the conductivity distribution of a domain.
