ABSTRACT

A singularity image method is applied to the electrical impedance tomography of gas-liquid flows in two-dimensional circular domain. Algorithms that use analytic complex functions, dipoles, and the Milne-Thomson circle theorem are described. Numerical experiments are provided to demonstrate the robustness of this technique. Numerical results show excellent reconstruction properties.
