Figure 3From: Rheological non-Newtonian behaviour of ethylene glycol-based Fe2O3 nanofluids Shear stress ( σ ) as function of strain ( γ ) at 10 rad s -1 for different concentrations. Solid circle, 5 wt.%; solid inverted triangle, 10 wt.%; solid square, 15 wt.%; solid diamond, 20 wt.% and solid triangle, 25 wt.%. The inset shows yield stress as a function of the nanoparticles concentrations.Back to article page
