In this numerical study,natural flow and heat transfer of nanofluids with Al2O3,TiO2,Cu and CNT nanoparticles in a vertical channel with dimpled fins at Rayleigh number(Ra)of Ra=3.25×107 to Ra=1×108 are investigated by using the finite volume *** obtained results revealed that,using CNT in volume fractions of 2%and 4%leads to significant heat transfer and atφ=6%,using TiO2 nanoparticles has a great effect on Nu number ***,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 *** general,according to temperature contours,reduction of wall temperature depends on the increase of Ra and volume fraction and the type of solid nanoparticles.
