Mass Flow Measurement of Biofuels using Electrical Capacitance Tomography

Biomass provides 10% of the global energy supply and electricity generation from biomass and waste is expected to increase by a factor of 4 by 2030. Currently efficiency of biomass power generation is poor and IEA targets improvements from 18% to 25% by 2030 [1]. Such increases in efficiency will require significant new technology and accurate real-time measurement of the flow of these highly v...

Multiphase 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-...

Application of Simulated Annealing and Genetic Algorithms to the Reconstruction of Electrical Permittivity Images in Capacitance Tomography

In this work we apply the simulated annealing (SA) and genetic algorithms (GA) inversion methods to the reconstruction of permittivity images from electrical capacitance tomography (ECT) measurements. The forward problem (i.e., to find the mutual capacitance data for a given permittivity distribution in the sensor) is calculated by using a finite-volume space discretization method in order to a...

Reconstruction of permittivity images from capacitance tomography data by using very fast simulated annealing

In this paper we introduce an image reconstruction technique for imaging permittivity distributions using electrical capacitance tomography, based on global optimization by very fast simulated annealing. Electrical capacitance measurement data are obtained between electrodes placed around the outer wall of an electrically insulating pipe. Such data are used to infer material distributions insid...

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...
