Abstract
In this work, some thermodynamic properties of nanoparticles, nanofluids containing a base fluid, and nanofluids with twodifferent baseswere assessed at the pressure range from 0.1 to 45 MPa and a temperature range from 273 to 363 K. this study focuses on nanofluids such as Al2O3, CuO, Co3O4, SnO2, TiO2-Rutile, TiO2-Anatase, ZnO and the base fluid containing H2O, Ethylene glycol and polyethylene glycol (with a molecular weight of 400). The used Equation of State (EOS) is the Tao–Mason (TM) equation of state which is based on statistical mechanics and its parameters can be calculated by a potential function. According to the quantum properties of nanoparticles, a quantum correction was used to calculate the second virial coefficient. To consider the polar effects of the material, the Morse three-parameter potential function was used which is more flexible than the usual two-parameter potentials functions such as Lenard Jones 6-12. Initially, the pure-component parameters of nanoparticles were fitted to the saturated liquid density data, and then the parameters were used for mixtures. Also, a binary parameter was fitted to consider the interactions between two different molecules in the mixtures. In total, from 1181 data points examined, the average absolute deviation between the calculated densities and the experimental ones is of the order of 0.5%. According to the results, this equation of state has good accuracy for calculating and predicting the density of nanofluids.
