DEVELOPMENT OF ELECTRICAL CAPACITANCE VOLUME TOMOGRAPHY (ECVT) AND ELECTROSTATIC TOMOGRAPHY (EST) FOR 3D DENSITY IMAGING OF FLUIDIZED BED SYSTEM

摘要

In this paper, Electrical Capacitance Volume Tomography (ECVT) is used to study a gas-solid fluidized bed system of .1 m ID. The interior flow structures (including the dynamic bed expansion, bubble/void breakage and particle movement) and the charge distribution in a gas-solid fluidized bed are illustrated based on the 3D images obtained from the ECVT.
