Abstract

An inverse problem is solved to obtain the particle concentration profile in suspension under pressuredriven flow with electrical impedance tomography (EIT). The finite element method (FEM) is employed in the forward problem and the regularized Newton-Raphson iterative method is used in the inverse problem. Different FEM meshes are used in the forward and the inverse problem not to commit inverse crime. To avoid post-calibration of measurement data, the complete electrode model is introduced. For the evaluation of the robustness of the reconstruction algorithm, several testing cases with measurement error are considered. The proposed algorithm can be used to reconstruct the particle concentration in suspension.
