Abstract

Laminar natural convective heat transfer of nanofluids inside an enclosure is numerically investigated considering the thermal dispersion effect of the nanoparticles. Feasibility of applying nanofluids instead of pure liquids in natural convective, which is a discrepancy issue between the previous numerical and experimental works, is examined. Results confirm the previous experimental results of general deterioration in heat transfer rate. Discussions, justifications and correlations for average Nusselt number are presented.
