Forced convection SiO2/water
nanofluid flow and heat transfer was numerically performed in 180-degree
three-dimensional curved duct with square cross section under steady and
laminar flow conditions in this investigation. Dean number was changed from 102
to 898. All surface of curved duct was exposed to uniform and constant heat
flux. Nanoparticle volume fractions was ranged
1.0%-4.0%. The average Nusselt number and average Darcy friction factor were
determined for each nanoparticle volume fractions. Velocity and temperature
profiles and secondary flows were analyzed in detail. In addition, numerical
study results are expressed with engineering correlations as changing average
Nusselt number and average Darcy friction factor with Dean number and
nanoparticle volume fraction.
