In this paper, combined convective heat transfer and nanofluids flow characteristics in a vertical rectangular duct are numerically investigated. This investigation covers Rayleigh numbers in the range of 2 � 106 ? Ra ? 2 � 107 and Reynolds numbers in the range of 200 ? Re ? 1000. Pure water and fiv...
