文摘
- •
Natural convection in square and triangular enclosures using nanofluids is studied.
- •
Thermal conductivity, viscosity, and density of SiO2/water nanofluid are measured.
- •
Nusselt number reduces for all types of enclosures with nanofluid concentration.
- •
Nusselt number is not a good criterion to determine the efficacy of nanofluids.
- •
Heat transfer coefficient ratio is maximized at low concentrations.
