Abstract :
In the two-phase flows measurement, Electrical Resistance Tomography and cross-correlation technique have both been proved available and promising. So in our investigation, the dual-plane ERT system is founded after combining the two techniques, and we proposed pixel correlation method to achieve the parameters of velocity and void fraction which are important to the measurement of two-phase flowrate. The experimental results of single bubble experiment and its analysis are also presented in this paper.
