A Simulation of Single and Segmented Excitation in Electrical Capacitance Tomography System
摘要
Soft field sensor is common with their forward problem which is the distribution of the sensitivity field throughout the target medium is not uniform. This paper concise the effect of single and segmented excitation in Electrical Capacitance Tomography for Gas-solid flow. The electrodes excitation for Protocol 1, Protocol 2, Protocol 3, and Protocol 4 were done to observe the potential value reading at the center of the pipe flow. The analysis on the potential value at the center of ECT sensor was done in COMSOL Multiphysics to determine the best excitation method. Results indicate that protocol 4 has 299.83% difference when compared to the single excitation in both homogenous and non-homogenous ECT system.
