The heat transfer and friction factors of developed turbulent flows in the stationary ribbed rectangular divergent channels have been investigated experimentally. The rectangular divergent channels with one sided ribbed surface only have the inclination angles of 0.72° and 1.43° at which the ribbed wall is manufactured with a fixed rib height (e) =10 mm and the ratio of rib spacing (p) to height(e) = 10. The measurement was conducted within the range of Reynolds numbers from 15,000 to 89,000. Because of the streamwise flow deceleration, the heat transfer characteristics of the rectangular divergent channels are quit different from those of the square straight channel. Thermal performances of the ribbed rectangular divergent channels are compared with the fibbed square straight channel under three constraints: identical mass flow rate, identical pumping power, and identical pressure drop. The comparison shows that among the two channels (D<SUB>ho</SUB>/D<SUB>hi</SUB> = 1.16 and 1.49) the divergent channel of D<SUB>ho</SUB>/D<SUB>hi</SUB> =1.49 has the higher thermal performance at the identical mass flow rate, and the divergent channel of Dho/Dhi ?1.16 has the higher thermal performance at the identical pumping power and static pressure drop.
