Voidage cross-sectional average

Optical fiber measurement of local solids concentrations of FCC catalyst fluidized in a 9-cm-i.d. column gave the results shown typically in Fig. 26. Analysis of these data showed that the radial voidage profile could be described solely by the cross-section-average voidage e, calculated as shown in Sec. 5.1, and the reduced radial coordinate r/R ... [Pg.533]

The preceding equation shows that as long as the cross-sectional average voidage E is known, then the three-dimensional voidage profile could be calculated. [Pg.115]
