Table 4.

Reference values of the packing factor $\overline{W_{\mathrm{ref}}}$ and diameter $\overline{D_{\mathrm{ref}}}$ obtained with the SFSE (0% SC), and values of the packing factor $\overline{W}$, diameter $\overline{D}$, and attenuation $\overline{{\alpha }_0}$ obtained with the SFSAE (0.25%, 0.5%, 0.75%, and 1% SC) at the shear rate 10 s⁻¹ in the Couette flow device. The parameter ϵ indicates the relative error and r² the correlation coefficient of the fitted SFSAE model on experimental data BSC_meas.
