Experiments study the turbulent heat transfer and friction for fully developed flow of air in a square channel with discrete rib turbulators. The discrete ribs are staggered on two opposite walls of the channel in alternate rows of three and two ribs. Nine rib configurations are examined: transverse ribs with an angle-of-attack () of 90, discrete ribs with = 90, parallel arrays of discrete ribs with = 45 and -45 on alternate rows, and parallel and crossed arrays of discrete ribs with = 60, 45, and 30. The rib height-to-hydraulic diameter ratio and the rib pitch-to-height ratio are 0.0625 and 10, respectively. The Reynolds number ranges from 10,000 to 80,000.
