Table 2 Thermophysical properties for nanofluid.
Properties | Nanofluid |
|---|---|
Density | \(\rho_{nf} = \, \left( {1 - \phi } \right)\rho_{bf} + \phi \rho_{sp}\) |
Heat capacity | \(\left( {\rho C_{p} } \right)_{nf} = \left( {1 - \phi } \right)\left( {\rho C_{p} } \right)_{bf} + \, \phi \left( {\rho C_{p} } \right)_{sp}\) |
Viscosity | \(\mu_{nf} = \, \left( {1 - \phi } \right)^{ - 2.5} \mu_{bf}\) |
Thermal conductivity | \(\frac{{k_{nf} }}{{k_{bf} }} = \frac{{k_{sp} - 2\left[ {k_{bf} - \phi \left( {k_{bf} - k_{sp} } \right)} \right]}}{{k_{sp} + 2\left[ {k_{bf} - \phi \left( {k_{bf} - k_{sp} } \right)} \right]}}\) |
