Research of Pixels Correlation Velocity Algorithm based on ECT

摘要

The two-phase flows play an important role in the industry process. They are common in modern industries, but the measurements of the two-phase flows have always been a challenge because of their complex three-dimensional behaviors As a result of the inconsistencies on the distribution of space and time, a new method with the resolution of the space and time is needed to measure the flow parameter. This article presents a method called pixels correlation to estimate the velocity distribution of gas-solid flow based on dual-plane electrical capacitance tomography system. To measure the velocity, the pixels correlation technology transfers it to the time interval measurement.
