Table 2 Applied formulation for the nanofluid properties
From: Simulation of CuO-water nanofluid natural convection in a U-shaped enclosure with a T-shaped baffle
Nanofluid properties | Applied model |
|---|---|
Density | \(\rho_{nf}=(1-\phi)\rho_f+\phi\rho_p\) |
Specific heat | \({\left(\rho C_p\right)}_{nf}=\left(1-\phi\right){{\left(\rho C_p\right)}_f+\phi{\left(\rho C_p\right)}_p}\) |
Thermal diffusivity | \(\alpha_{nf}=k_{nf}/{(\rho C_p)_{nf}}\) |
Thermal expansion coefficient | \({(\rho\beta)_{nf}}=(1-\phi)\rho_f+\phi\rho_p\) |
Dynamic viscosity | \(\mu_{nf}=\frac{\mu_f}{{(1-\phi)}^{2.5}}\) |
Thermal conductivity | \(k_{nf}=k_f\left[\frac{\left(k_p+2k_f\right)-2\phi\left(k_f-k_p\right)}{\left(k_p+2k_f\right)+\phi\left(k_f-k_p\right)}\right]\) |
