Viscosity ( η ) vs. shear () rate of EG/TiO 2 nanofluids at different temperatures. Flow curves for ( a ) A-TiO2/EG and ( b ) R-TiO2/EG at 25 wt.% mass concentration and at different temperatures: square, 283.15 K; circle, 293.15 K; triangle, 303.15 K; diamond, 313.15 K; cross mark, 323.15 K. ( c ) Energy of activation to fluid flow (E a ) vs. shear rate for A-TiO2/EG (filled diamond) and R-TiO2/EG (empty diamond) 25 wt.% nanofluids.
