Dimensionless representation of material functions

As a rule process engineering measurements in the laboratory are carried out with the aim of supplying design data for the industrial plant. For this purpose it is required that a complete similarity exists between the process on laboratory-scale and that on industrial-scale, which is expressed in identical numerical values for the process-describing numbers Hi = idem (see Section 1.6, Dimensional analysis). [Pg.57]

Assuming that a non-Newtonian fluid participates in the process and the Reynolds number Re ff = is the applying process number. Since /Zeff depends for [Pg.57]

Pawlowski [428, 429] indicated that the rheological properties of many non-Newtonian fluids can be described by material parameters, whose dimensional matrix had the rank of 2. By reasonable combination these material parameters could be transformed into two dimensional material constants  [Pg.57]
