一种在气-液两相流或液相流中流动特性的测量系统,其结构简单、操作方便、实用性强;它可以自动地移动测量探针、进行多通道的数据采集和对实测数据进行实时处理;采样频率可达几十万赫兹; 这个系统适用于处理各种仪表输出的模拟或数字信号。本文描述了测量气泡速度、气泡大小、含气率、混匀时间和剪切应力等的电位探针和电化学技术。这个系统在许多实验中得到应用。
A measuring system for the flow characteristics in a gas-liquid two-phase flow or a liquid-phase flow has the advantages of simple structure, convenient operation and high practicability; it can automatically move the measuring probe and perform multi-channel data acquisition and measurement of the measured data For real-time processing; sampling frequency of up to hundreds of thousands of hertz; This system is suitable for processing a variety of instruments output analog or digital signal. This article describes potential probes and electrochemical techniques that measure bubble velocity, bubble size, gas content, mixing time, and shear stress. This system has been used in many experiments.
