Velocity Measurement of Multi-Phase flows Based on Electrical Capacitance Volume Tomography

Abstract

In this work, a novel 3D velocimetry systems based on electrical capacitance volume tomography (ECVT) is introduced. Unlike traditional 2D velocity systems, the current system provides three dimensional velocity maps of multi-phase flows inside a conduit directly from the reconstructed image. Here, the velocity measurement process starts by acquiring capacitance data from the ECVT sensor. An image reconstruction algorithm is then used to reconstruct whole volume images directly from the three dimensional capacitance sensors. The sequence of reconstructed images from the ECVT system is used to obtain three dimensional velocity maps. Using ECVT technology for mapping velocity profiles; presented in this work; is the first to be reported.
