A novel method of modeling and simulation for electrical resistance tomography system

A new method of modeling and simulation for electrical resistance tomography (ERT) system applied to two phase flow measurement is presented in the paper. Based on the Matlab PDE (partial differential equations) tool box, the mathematical model is established, the forward problem is solved and the distributions of electric potential and current density in sensitive field are obtained. The results are verified by ANSYS. It has an important theoretical significance for the research of sensitive field and image reconstruction of ERT.
