| 中文摘要 | This paper presents an impedance image based method, which is known as electrical resistance tomography (ERT), for characterization of gas-water two-phase flow in a 40m horizontal flow loop. An ERT sensor based on conductive ring technique is used to overcome the problem of measurement saturation caused by electrodes loosing electrical contact with conductive liquid, as it often occurs in stratified flow and slug or plug flow. In previous study, data implementation was constrained by the limited data collection speed and insufficient auxiliary sensing information. The quality of impedance images was also decayed due to the use of a linear back-projection algorithm. In order to gather sufficient information for the implementation of flow characteristics particularly flow pattern recognition and air cavity velocity, a fast data collection strategy was applied to a dual-plane ERT sensor and an iterative algorithm was used for image reconstruction. Results, in respect to flow patterns and velocity maps, are reported. |
