摘要：

The dynamic characteristics of gas-solid how patterns within a circulating fluidized riser have been investigated using an electrical capacitance tomography system. The tomograms show both an instantaneous and an average in time solids' distribution in the riser cross-section. The effects of gas superficial velocity and solids circulating fluxes on the flow behaviour were measured and the results compared with data from the existing literature.
