Abstract
This paper presents preliminary results of imaging the flow on a thick pipe with electrical capacitance tomography (ECT). As a contrast, the images on thin pipe are also given. The study is based on numerical simulation with COMSOL and MATLAB. The pipe thickness of the ECT sensor is 2 and 12 mm, respectively. The capacitances and sensitivity maps are analyzed before image reconstruction. Flow patterns used in the study include annular flow, bubbly flow, core flow, and stratified flow. To improve the quality of image reconstructed in the thick pipe, the capacitances of adjacent electrodes are eliminated. At the end of the paper, analysis is conducted in terms of relative image error for different flow patterns.
