Thermo physical properties of γ Al₂O₃-Water/Ethylene Glycol nanofluids [6, 7, 8, 9, 16, 17, 18, 19].

Properties	γ Al2O3– H2O
Effective dynamic density	${\rho }_{nf}=\left(1-\phi \right){\rho }_f+\phi {\rho }_s$
Heat capacitance	${\left(\rho C_p\right)}_{nf}=\left(1-\phi \right){\left(\rho C_p\right)}_f+\phi {\left(\rho C_p\right)}_s$
Dynamic viscosity	$\frac{{\mu }_{nf}}{{\mu }_f}=123{\phi }^2+7.3\phi +1$
Effective thermal conductivity	$\frac{k_{nf}}{k_f}=4.97{\phi }^2+2.72\phi +1$
Thermal expansion coefficient	${\left(\rho \beta \right)}_{nf}=\left(1-\varphi \right){\left(\rho \beta \right)}_f+\varphi {\left(\rho \beta \right)}_s,$
