- How should we proceed to guarantee that the results obtained at
lab-scale will be also scalable at industrial scale?
Until now, most of works encountered in the literature did not
take care about these questions: they simply consist in replacing
the Newtonian viscosity by an apparent viscosity defined from the
Ostwald–de-Waele’s model in which an average shear rate is considered
according to the well-known concept of Metzner–Otto:
˙ av = KMO · N
