摘要
气液两相流流型识别是气液两相流参数检测中需解决的关键技术之一。采用自主设计的气液两相流信号源发生装置,产生泡状流、弹状流及环状流等流型,满足气液两相流的标定需要。基于红外检测技术实现对气液两相流各种流型条件下截面空隙率的测量,并对采集数据处理求解实现流型识别。试验结果表明:红外检测技术能够实现气液两相流各种流型的识别,并测量出对应的空隙率,满足工程应用需要。
The gas-liquid two phase flow regime identification is one of the key technologies for measuring void fraction of gas-liquid two phase flow. The bubble flow, slug flow, and annular flow stream are produced by independent design of the gasqiquid two-phase flow source device to meet the need of gas-liquid two-phase flow calibration. The gas-liquid two phase flow regime identification is solved by the signal of various flow conditions. The result shows that the infrared detection technology is able to achieve gas-liquid two phase different flow regimes identification and measure the void fraction to meet the needs of engineering applications.
