本文探讨了将电容耦合式非接触电导测量(Capacitively Coupled Contactless Conductivity Detection,C4D)技术应用于毫米级管径气液两相流气泡速度测量的可行性,提出了一种结合C4D技术及互相关测速原理的气泡速度测量新方法.研究包括两个部分:首先,结合串联谐振原理,研制了一种适用于气泡速度测量的新型三电极C4D传感器;其次,利用所研制传感器获得的两组电导信号,根据互相关测速原理实现气泡的速度测量.作为初步研究,在内径6.0 mm的竖直管内进行了气泡速度测量实验.实验结果表明将C4D技术运用于毫米级管径气液两相流气泡速度测量是可行的,所提出的气泡速度测量方法是有效的.
