Figure I 1.5. Viscosity of polystyrene with dissolved R-152a at 150 °C measured as a function of shear rate. The Schummer correction and a pressure correction have been applied, as described in the text, to obtain isobaric viscosity curves corresponding to the back-pressures applied during the measurements. The R-152a composition and back-pressure values are O 5.6 wt% R-152a, 12.06 MPa 7.0 wt%, 12.48 MPa A 8.3 wt %, 17.18 MPa V 10.4 wt%, 16.41 MPa. The solid curve is the viscosity curve for pure polystyrene at 150 °C and 1 atm pressure. Data from Kwag (1998).

Conventional stirred-tank polymeric reactors normally use turbine, propeller, blade, or anchor stirrers. Power consumption for a power-law fluid in such reactors can be expressed in a dimensionless form, Ne = Reynolds number based on the consistency coefficient for the power-law fluid. Various forms for the function f(m) in terms of the power-law index have been proposed. Unlike that for Newtonian fluid, the shear rate in the case of power-law fluid depends on the ratio dT/dt and the stirrer speed N. For anchor stirrers, the functionality g developed by Beckner and Smith (1962) is recommended. For aerated non-Newtonian fluids, the study of Hocker and Langer (1962) for turbine stirrers is recommended. For viscoelastic fluids, the works of Reher (1969) and Schummer (1970) should be useful. The mixing time for power-law fluids can also be correlated by the dimensionless relation NO = /(Reeff = Ndfpjpti ) (Tebel et aL 1986).
