Algorithm base on gamma-ray computed tomography method for gas-solid flow time average concentration in cyclone
A new approach to the gamma-ray densitometry tomography(GDT) technique was proposed for measurement of gas-solid flow in cyclone, where the time average concentration field can be simplified to continuous function and symmetry system, based on only one bunch of through the regional centers ray and another distance the center d positions ray data, through the measurement of body. So it realized faster data acquisition and image reconstruction, and possessed both the continuous function models high gradient of radial concentration distribution and highly accuracy. Due to the collected data were severely diminished, the method sharply reduced the cost of image scans mobile system. The numerical simulation proved the accuracy of that algorithm base on gamma-ray computed tomography method for gas-solid time average concentration field in cyclone.
