摘要
基于电容层析成像技术(ECT),提出一种快速在线气液两相流流型识别新方法。实验表明,该方法简便易行,对于层状流、环状流、核心流以及塞状流均具有较高的识别准确率,可以满足工业在线运行需要。
Two-phase flow is a nonlinear complex system.The flow pattern identification is important for industrial process control.A new method is proposed for gas-liquid two-phase flow pattern identification.The test results show that the method is effective.The identification results of stratified flow,annular flow,core flow and plug flow are satisfied for the requirements of the industrial operation online.
