Fusion of Capacitance Tomography with Ultrasound Tomography

Many multi-phase flow applications in industrial processes like design and monitoring of bubble column reactors or in oil-well industry require the accurate measurement of void fractions and velocities. A cheap and robust method to obtain process relevant quantities is Electrical Capacitance Tomography (ECT). Since ECT is sensitive to bulk information while knowing to respond insensitive to interfaces, ECT is augmented with information obtained with ultrasound, which is sensitive to interfaces. Additionally in this project we focus on 3D reconstruction, since it is well known that the accuracy, which is necessary for industrial processes, cannot be achieved with a 2D approximation of the problem.
