Abstract

In this paper, different algorithms used in conventional electrical capacitance tomography, such as, Landweber method, Tikhonov regularization method and Linear Back Projection method have been explored in regard to water-dominated vertical flows. Imaging of multiphase flows holding water as continuous phase (i.e. water-dominated flows) is a very challenging task because of the high permittivity of water. However, as opposed to existing literature, it is shown that it is still possible to image water-dominated flows with conventional electrical capacitance tomography. A comparison among the effectiveness of different methods for successful image reconstruction of different types of vertical flows has been presented as well. This work shows a potential direction towards imaging water-dominated multiphase flow using electrical capacitance tomography.
