Abstract
We have reported that the gas-solid contacting index（V0） is eligible to evaluate the fluidization quality of a gas fluidized solid bed, which is obtained easily from the analysis of the current method oscillogram.
In the range of gas velocity ratio to minimum fluidization velocity of the particles（Uo/Umf） from 1.5 to 7.0. It was found that there is a linear relationship between the gas cross flow coefficient(Kb) and the gas-solid contacting index(VD), and that the proposed contacting index was one of the most useful and simplest index for the prediction of the fluidization quality.
