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.
Using computational fluid dynamics modelling to study the mixing of pseudoplastic fluids with a Scaba 6SRGT impeller.
These fluids can be pseudoplastic fluids, which have lower viscosity with increasing shear rate applied.
Besides the dependence of the rate, the pseudoplastic fluids can be thixotropic, also dependent on the time of shearing.
In general C(n)m must be small for moderate pseudoplastic behavior and large for highly pseudoplastic fluids as shown in Fig.
Lesser pseudoplastic fluids (more crystalline polymers) have a high fluidity.

Dilantant fluids, such as cornstarch/water mixtures and some candy compounds, exhibit increasing viscosity with increased shear rate; pseudoplastic fluids
, such as ketchup, decrease in viscosity as shear rate increases; thixotropic fluids, such as chocolate, molasses and fruit-juice concentrates, lose viscosity over time under a constant shear rate.
3 also reveals that the nanogel dispersions are pseudoplastic fluids
with lower viscosities at 25[degree]C.
