The investigated aqueous xanthan gum solutions exhibit the behavior of
pseudoplastic fluid that is expected for xanthan gum (Diaz, Vendruscolo, & Vendruscolo, 2004; Rottava et al., 2009).
For a Newtonian fluid n =1, for a dilatant fluid n >1 and
pseudoplastic fluid n <1).
For a fluid with 0 < n < 1, the effective viscosity decreases with shear rate, and the fluid is called shear-thinning or
pseudoplastic fluid.
Power law fluid is non-Newtonian model, which usually includes
pseudoplastic fluid and expansion plastic fluid.
The semisolid aluminum alloy slurry is
pseudoplastic fluid [24].
All the gum solutions showed
pseudoplastic fluid behavior, as expected for xanthan gum.
They have studied the shape and the size of cavern generated around a radial-flow Scaba 6SRGT impeller in the mixing of xanthan gum solution, which is a
pseudoplastic fluid possessing yield stress.

Non-Newtonian fluids include Bingham plastic fluid,
pseudoplastic fluid, and expansion fluid, depending on different rheological properties [15].
At low shearing rate range (ln [[??].sub.m] < 5), the ln [[eta].sub.a] of various nanocomposites are nearly unchanged with increasing shearing rate, belonging to the Newtonian fluid; while at high shearing rate range (ln [[??].sub.m] > 5), the ln [[eta].sub.a] of various nanocomposites decreases sharply with increasing shearing rate, belonging to the
pseudoplastic fluid, due to the disentanglements between the molecular chains or between the molecular chains and nanoparticles.
