FLOW VELOCITY MEASUREMENT METHODS USING ELECTRICAL CAPACITANCE TOMOGRAPHY


Abstract

The current methods of calculating the velocity field based on a twin-plane electrical capacitance system for multiphase flows are presented. The described methods allow to calculate the velocity profile of the multiphase flow in cross-section of industrial installation. The theoretical assumptions of the considered methods are also noticed. The main advantages and disadvantages of the authors’ flow velocity measurement methods are discussed.
