Abstract EN
This numerical study is aimed at investigating the forced convection heat transfer and flow characteristics of water-based Al2O3 nanofluids inside a horizontal circular tube in the laminar flow regime under the constant wall temperature boundary condition.
Five volume concentrations of nanoparticle, 0.1, 0.5, 1, 1.5, and 2 vol.%, are used and diameter of nanoparticle is 40 nm.
Characteristics of heat transfer coefficient, Nusselt number, and pressure drop are reported.
The results show that heat transfer coefficient of nanofluids increases with increasing Reynolds number or particle volume concentration.
The heat transfer coefficient of the water-based nanofluid with 2 vol.% Al2O3 nanoparticles is enhanced by 32% compared with that of pure water.
Increasing particle volume concentration causes an increase in pressure drop.
At 2 vol.% of particle concentration, the pressure drop reaches a maximum that is nearly 5.7 times compared with that of pure water.
It is important to note that the numerical results are in good agreement with published experimental data.
