Abstract
Displacement-current phase tomography (DCPT) is a process tomographic technique originally proposed to overcome the limitations of electrical capacitance tomography (ECT) for two-phase flows where one phase is electrically conductive, such as water. Both DCPT and ECT are two-dimensional crosssectional imaging techniques. In this paper, two new developments based on DCPT are described. First, we describe the extension of DCPT to perform direct volumetric imaging. Second, a new method for fluid flow velocimetry (three-dimensional velocity profiling) based on volumetric DCPT is proposed. Simulation and experimental results are provided to demonstrate the proposed techniques for imaging of water-dominated vertical flows.Keywords
