Electrical impedance imaging of two-phase flows undergoing rapid transient: Part II. Effect of input current pattern

In this study, the electrical impedance imaging of two-phase flows undergoing rapid transient is considered with a special emphasis on the effect of the current pattern on the image reconstruction. As observed in the companion paper, the trigonometric current pattern, which is commonly used in the conventional static electrical impedance imaging, shows poor performance in case of the dynamic imaging considered in this work. Extensive numerical experiments are conducted with various kinds of current patterns and their effects on the image reconstruction performance are examined. The results indicate that the trigonometric patterns with lower modes are preferable.
