  • 摘要:

    气液两相流作为一种工业领域中普遍存在的流态,在测量时需考虑气相和液相间的速度差。相较于流动规律平稳的气相而言,研究不稳定的气泡流动状态具有更高的技术难度。本文针对空气-水为工质的两相流中一项重要参数——气泡速度进行测量,引入基于互相关运算的电磁检测方法,通过提高系统激励频率得到较大的检测信号。实验设计了高频(>1 MHz)电磁检测系统,选用垂直上升管道,并在管道的2个平行截面分别安装电磁传感器,每组传感器均包含一个激励线圈及一个接收线圈,对2组接收线圈上的相位信号进行互相关运算,从而求得气泡的速度。实验中,对3种不同速度气泡采集到的信号进行了对比分析,相对误差控制在10%以内,提供了一种完全非接触非侵入的测量气泡速度的方法。此方法可以进行后续补充完善,用于其他工业场合,如金属液中气泡参数的测量等。
