Abstract

电阻层析成像(ERT)技术具有快速、非侵入性及可视化的特点，优于常规方法及其它层析成像模式，已在气液(固)多相流动体系中得到广泛应用。本工作以气液(固)多相流动体系为研究对象，介绍了ERT测试工作原理，分析了ERT与其它多相流检测技术的特点，综述了ERT在多相流动3个重要特性和过程参数测量中的应用进展，指出了ERT技术应用过程中需要解决的问题(流型辨识的标准化、识别过程参数的准确性、时间分辨率和空间分辨率均衡化等)。ERT作为流体流动的可视化工具，在优化电极阵列、图像重建算法或建立三维(四维)场模型的基础上，提出了工业过程参数动态信息与流体力学数值模拟相结合的模式，可有效验证数学模拟的准确性，延伸了其应用领域。

Key words： Electrical Resistance Tomography (ERT); multiphase flow; parameter identification; process control; optimal design
