摘要

Abstract

In this numerical study

natural flow and heat transfer of nanofluids with Al

TiO

Cu and CNT nanoparticles in a vertical channel with dimpled fins at Rayleigh number (

) of

= 3.25×10

= 1×10

are investigated by using the finite volume method. The obtained results revealed that

using CNT in volume fractions of 2% and 4% leads to significant heat transfer and at

= 6%

using TiO

nanoparticles has a great effect on Nu number enhancement. Also

using solid nanoparticles in base fluid causes more uniform heat transfer distribution

especially in areas close to heated surface and by adding more volume fraction in base fluid

temperature level reduces. In general

according to temperature contours

reduction of wall temperature depends on the increase of Ra and volume fraction and the type of solid nanoparticles.
