Abstract

The present study investigated the effects of four parallel rib arrangements on heat/mass transfer and pressure drop characteristics in rotating two-pass ducts. The experiments of mass transfer and pressure measurement are performed to obtain heat transfer distributions and friction losses. The highest averaged heat (mass) transfer and friction loss in each region appeared in the turning region in the stationary cases, but appeared in the upstream region of the second pass in the rotating cases. Among the tested rib arrangements, the averaged heat (mass) transfer and the friction factor in the second pass in the stationary ducts were high in the cases with the NN- and PP-type ribs; however, in the rotating ducts, they were high in the cases with the NN- and PN-type ribs. The thermal performance in the four different rib arrangements was almost the same.
