Figure 5From: Rheological and volumetric properties of TiO2-ethylene glycol nanofluidsExcess molar volumes of nanofluids V m E . Molar excess volumes vs. molar fraction for different EG nanofluids at 303.15 K and 20 MPa. Filled circle, A-TiO2/EG; filled triangle, R-TiO2/EG; empty triangle, Fe3O4/EG [38]; empty diamond, Fe2O3/EG [38]; empty circle, (48-nm ZnO)/EG [39]; empty square, (4.6-nm ZnO)/EG [39].Back to article page
