Abstract
To alleviate the ill-posedness and non-linearity of electrical capacitance tomography, Bayesian maximum entropy (BME) mapping method is used to mix another source of information. They are some observation points, which are hard data. They can be seen as error free. Three two-phase flow patterns are preset to verify the method. Results show that the BME prediction maps are more accuracy than ECT reconstructed image. BME images have more clear edges and those sizes are more similar to the original maps. Two quality assessments demonstrate that BME maps has a lower relative error(RE) and higher correlation coefficient(CC), which verify the effectiveness of the BME mapping method in fluid measurement.
