| Résumé : | The output of electrical capacitance tomography measurements of gas/solids flow in a vertical pipe have been analyzed to extract flow pattern information. Two approaches already used for gas/liquid flows were employed. One uses the shape of the probability density functions of the cross-sectionally averaged gas fraction time series. The other considered the velocities of periodic structures, i.e., pulses of particles. The results from both techniques showed that a flow pattern similar to churn flow in gas/liquid flow was indicated. When the gas/solids flow rates are plotted on a gas/liquid flow pattern map, they fell in the churn flow region. |
