摘要
对目前几种用于测量低温气液两相流空泡率方法的基本原理、传感器结构及国内外研究情况进行了综述,包括辐射法(射线吸收法)、微波法、射频法、电容法,分析了4种方法的优缺点,在比较4种方法的基础上,提出了目前采用电容传感器测量气液两相低温液体空泡率的优势及设计准则。
The basic principles and sensor construction of several methods used for measurement of void fraction in cryogenic two-phase flow were reviewed, including attenuation sensors, microwave type, RF sensors, and capacitance type. Based on the analysis and comparison of various measurement techniques, the advantage of capacitance type method was presented and design fundamentals were given.
