An experimental investigation of heat transfer in a rectangular channel (aspect ratio AR equal to 5) with angled rib turbulators, inclined at 45 deg, is presented. The angled ribs (of square section, size e) were deployed with parallel orientations on one or two surfaces of the channel. Four values of the rib pitch p were considered in order to investigate the range of the rib pitch-to-height ratio p/e from 6.66 to 20.0. The convective fluid was air, and the Reynolds number varied from 9000 to 35500.
