Figure 4From: Rheological non-Newtonian behaviour of ethylene glycol-based Fe2O3 nanofluids Storage ( G ') and loss ( G ″) moduli. As a function of frequency for EG/Fe2O3 nanofluids at 1% strain: (solid circle, empty circle) 5 wt.%; (solid inverted triangle, empty inverted triangle) 10 wt.%; (solid square, empty square) 15 wt.%, (solid diamond, empty diamond) 20 wt.% and (solid triangle, empty triangle) 25 wt.%.Back to article page
