摘要

本文通过对两相流体电容层析成像中的敏感场的分析与研究，指出了旧算法中对不同的流体分布采用同一加权因子是造成管道中心处成像精度低的原因，提出了针对不同流型采用不同加权因子的迭代算法．计算机模拟的结果表明，经过改进以后的算法对各种相浓度分布的成像结果都有明显的改善，证明该算法比以前有较大进步

Abstract

This paper investigates the sensitivity distribution of two phase flow electrical capacitance tomography

and points out that the cause of low image reconstruction fidelity at the pipe center is that the former algorithm uses the same weighting factor in different flow type.It presents a new iterative algorithm using different weighting factor in different flow type.According to the result of computer simulation

this improved algorithm is able to greatly increase the imaging fidelity of any flow phase concentration.It’s proved to be better than before.
