Electrical Capacitance Tomography System
Electrical Capacitance Tomography is a non intruding technique used in industries. It is based on measuring the capacitance of multi-electrode ECT sensor produced by the change in dielectricity or due to change in concentration of material. With the use of computed values, a cross sectional image of the material placed in the dielectric medium is obtained. ECT system can be used in chemical fie...
متن کاملMultiphase permittivity imaging using absolute value electrical capacitance tomography data and a level set algorithm.
Multiphase flow imaging is a very challenging and critical topic in industrial process tomography. In this article, simulation and experimental results of reconstructing the permittivity profile of multiphase material from data collected in electrical capacitance tomography (ECT) are presented. A multiphase narrowband level set algorithm is developed to reconstruct the interfaces between three-...
متن کاملModelling Surface Tension Dominated Multiphase Flows Using the Vof Approach
Low-capillary number or surface tension dominated flows are found in a number applications, ranging from small scale microfluidics up to larger scale analysis of microgravity sloshing. This paper evaluates the possibility of modelling of surface tension dominated multiphase flows using an Eulerian volume-of-fluid (VOF) approach with high-resolution surface capturing. With the aim of improved st...
متن کاملElectrical Capacitance Tomography System For Industrial Applications
An electrical capacitance tomography system (ECT) has been developed. The system consists of a circular sensor with 8 electrodes. A charge generator injects charges into the sensor filled with objects different dielectric constants. The charges, in the form of potential dropped, on another electrode are measured and acquired digitally to a PC for calculating the capacitance and estimating the d...
متن کاملMultiphase Flow Imaging by Capacitance Tomography Using Simulated Annealing Inversion
Electrical capacitance tomography (ECT) is a technique for obtaining crosssectional images of the electrical permittivity distribution inside an electrically non-conducting body. It can be used to map the composition of two-phase mixtures like gas-oil systems and provides a useful tool for multiphase flow visualization and measurement and potential applications in petroleum industry. The ECT se...
