Abstract :
A method of image reconstruction of electrical capacitance tomography applying to unknown permittivity object in two-phase flows is studied in the paper. An one-simulation-calibration method is provided, which implements simulation calibration when the pipe fills with high and low permittivity medium respectively, and combines with iterative algorithm to realize image reconstruction for unknown permittivity object. The results of simulation and experiment show that the image of unknown permittivity object can be well reconstructed and the two-phase flows concentration can be measured as well.
