摘要
介绍应用电阻层析成象 (ERT)技术测量两相流中的基本原理和ERT系统的基本结构 ;描述应用天津大学过程层析成象研究室开发的ERT系统样机 ,在实验装置上进行两相流流型识别的实验研究。提出应用ERT系统进行流型识别的基本方法 ;并通过重建图像和分析测量数据实现两相流流型的识别。
This paper introduces the principle of two phase flow using Electrical Resistance Tomography(ERT) and construction of ERT system.The ERT prototype developed in Tianjin University regimes is described.The experiments of two phase flow measurement are finished at different experiment set up.The methods of identification of two phase flow regime using ERT system are published.Through image reconstruction and data handling,the identification of flow regime are realized.The result shows that regime identification and some relative parameters measurement of two phase flow are possible by ERT system.
