Abstract:
In this study, heat transfer due to forced convection of Al2O3-H2O nanofluid flow over an isothermal
cylinder has been nume rically investigated. Governing equations containing continuity, N–S equation and
energy under steady state have been solved using finite volume method. Here, the Reynolds number (Re) are
varying from 10 to 40 and the volume fractions (φ) are considered here are 0% to 5%. The effect of volume
fraction of nanoparticles on fluid flow and heat transfer were investigated numerically. It was found that at a
given Nusselt number, drag coefficient, re-circulation length, and pressure coefficient increases by increasing the
volume fraction of nanoparticles
