DYNAMIC VOIDAGE MEASUREMENTS IN A GAS SOLID FLUIDIZED BED BY ELECTRICAL CAPACITANCE TOMOGRAPHY
Chem. Eng. Comm., 190: 1395-1410, 2003,-0001,():
Based on the electrical capatitance tomography tehnique, a voidage measurment system that can implement a voidagedistribution display and voidage measurement of a gas-solid fluidized bed sumultaneously is developed. The back projection algorithm is selected as the image reconstruction algorithm to satisfy the requeiremnt of voidage distribution display. Combining the Tikhnovregularization principle with the ART algorithm. A new quantitiative hybrid image reconstruction algorithm is presented to implement the voidage measurement of a gas-solide fluidized.Experimental results show that the developed measurement sysytem is successful. The speed of image reconstruction of voidage distribution is greater than 20 frames per second. The maximum error of voidage measurement can be less than 5%.
