Abstract
<div><div>The present study reports numerical simulations of three-dimensional</div><div>laminar mixed convection heat transfer of water-based-Al2O3 nanofluid in an open </div><div>cubic cavity with a heated block. Ansys-Fluent 14.5 was used to simulate 3D flows</div><div>with heat transfer. Streamlines, isotherms, vertical velocity profile, and local Nusselt</div><div>numbers are presented for Reynolds numbers in the range (300<Re<700), volume</div><div>fractions of nanoparticles (0<ϕ<0.08) and heat source location (1cm <d <3cm). It was</div><div>found that when adding nanoparticles to the base fluid or increasing the volume</div><div>fraction of nanoparticles, the Nusselt number increases. Moreover, the heat transfer rate</div><div>increases when the Reynolds number increases.</div></div><div><br></div>
