The analysis used a two-dimensional enclosure under natural convection heat-transfer conditions and has been carried out for the Rayleigh number in the range of 103 < Ra < 105, and for the Au nanoparticles' volume-fraction range of 0 < j < 0.10. We report highly accurate numerical results indicating clearly that the mean Nusselt number is an increasing function of both Rayleigh number and volume fraction of Au nanoparticles. The results also indicate that a heat-transfer enhancement is possible using nanofluids in comparison to conventional fluids. However, low Rayleigh numbers show more enhancement compared to high Rayleigh numbers"},{"@xml:lang":"sl","#text":"V prispevku smo numerično analizirali prenos toplote v koloidnih disperzijah nanodelcev zlata v vodi (Au-nanotekočine).

Rezultati analize kažejo, da je srednje Nusseltovo število naraščajoča funkcija obeh, tako Rayleighevega števila kot volumenskega deleža Au-nanodelcev. Prikazani rezultati nakazujejo, da lahko prenos toplote izboljšamo z uporabo Au-nanotekočin namesto navadnih tekočin.
