... and 0.04 to 0.053, respectively. In contrast, the flow parameter, like the Reynolds number, is kept in the range of 4 × 10 3 to 18 × 10 3 . A maximal performance evaluation criterion of 1.51 is attained for the W-shape ribs with a non-dimensional pitch of 7.14 and a non-dimensional height of 0.047...

... augmentation in Nu and f over the smooth duct was obtained as 4.01 and 4.28 times, respectively, at the optimum value of d/W = 0.35 and g/e = 2 under similar flow conditions. The maximum value of THPP obtained at d/W and g/e of 0.35 and 2, respectively, and Reynolds number of 12,445. 1 Corresponding...

... solar air heater having an aspect ratio of 4. The absorber surface was heated uniformly by a constant heat flux of 800 W/m 2 . The non-dimensional roughness parameter considered was relative roughness pitch, i.e., P/e, and its values range between 5 and 12 with Reynolds number (Re) ranges between 6500...
