Krieger-Dougherty relation

FIGURE 11.13 Viscosity vs. volume solids loading. Krieger-Dougherty relation. For small loading (<5%) it is linear as predicted by Einstein. [Pg.74]

This is one form of the Krieger-Dougherty relation, which for (f— 0 and... [Pg.277]

In Figure 7.7, the plots of r vs. < > calculated from Simha s Eq 7.24, Mooney s Eq 7.28, and Krieger-Dougherty s Eq 7.8 are compared with the empirical curve-htted relation, Eq 7.5. For all the relations, the intrinsic viscosity [t]] = 2.5 was used. However, to optimize the fit, different values for the maximum packing volume fraction, ( ) = 0.78, 0.91, and 0.62 respectively, had to be used. Detailed analysis of Thomas data made it possible to conclude... [Pg.460]

If the filler has some trend to cluster in aggregates, one could somewhat further develop the Krieger-Dougherty type of equations by considering an effective enhanced volume fraction. Such an effective volume fraction could then be related to both the overall size of the cluster D and the size of the single particles d with respect to fractal considerations. Equation 6.8a would then be rewritten as ... [Pg.274]

Krieger and Dougherty (1959) proposed the closely-related formula... [Pg.20]

The viscosity data of Figure 5 can be reduced to a single curve by replotting nr as a function of /o indicating that the relative viscosity at zero shear rate is a unique function of /0 A relation between dispersion viscosity and

0, derived by Mooney (5) and modified, by Krieger and Dougherty (6), gives... [Pg.105]

The relative viscosity is related to the volume fraction g> by the Dougherty- Krieger equation [40] for hard spheres,... [Pg.154]

The second dependence, is the already cited Equation 7.8, derived by Krieger and Dougherty [1959]. The relation belongs to a large group of dependencies of the type, discussed in detail a few years back [Utracki, 1989] ... [Pg.460]

To derive a more general relation for the phase inversion concentration, one may start by computing r](A) = t BT r( A) t (B) = tiArij( B), where rjr is the relative viscosity. The latter dependence can be expressed as (Krieger and Dougherty 1959)... [Pg.732]
