Mass flow measurements based on a virtual channel concept

Abstract

The development of the mass flow rate measurements in the industrial systems using a twin-planes electrical capacitance tomography (ECT) system is presented. The mass flow measurement is based on cross-section decomposition into homogenous regions and virtual channel is then defined as connecting of two homogenous regions of different sensor planes. The decomposition has been obtained by using a stochastic flow model. As a result the set of virtual channels is obtained instead the complex flow inside a single physical channel. The authors present the results of investigation for turbulent flow propagation using the virtual channel concept also.
