The xanthan gums, produced from the alternative medium SSAE using three different strains of Xanthomonas campestris,gave K and n values typical of pseudoplastic fluids
. The native strain 1182 showed the best performance with respect to the K and n values, the percentage of substrate used, and the viscosity.
The agitation of pseudoplastic fluids
results in the formation of a well mixed region (cavern) around the impeller and essentially stagnant and/or slow moving fluids elsewhere in the vessel.
These fluids can be pseudoplastic fluids
, which have lower viscosity with increasing shear rate applied.
The results show that the behavior of TFB is consistent with that of a pseudoplastic fluid
, and the Herschel-Bulkley model is more applicable to TFB.
PTT/CaC[O.sub.3] nanocomposites' melt belongs to the pseudoplastic fluid
, and the pseudoplasticity increases with the increasing CaC[O.sub.3] content.
The lower limit of this curve corresponds to a very pseudoplastic fluid
(n [is less than] 0.35).
become thinner when the shear rate increases, until the viscosity reaches a plateau of limit viscosity.

: Analytical results and exact solutions.
Graphs for pseudoplastic fluids
are given in Figures 4 and 7.
A reader posits that both are, erm, non-Newtonian pseudoplastic fluids

Measured and computed velocity profiles for laminar flow of yield pseudoplastic fluids
in concentric and eccentric annuli have been given also by Escudier et al.
