Experiments were conducted to investigate the effects of rotation and aspect ratio on the convective heat transfer of radiallyoutward air flows in rotating rectangular ducts with a uniform wall heat flux by using fiberglass duct walls lined withseparated film heaters. The duct hydraulic diameter, heater active length, and mean rotation radius were 4, 120, and 180 mm,respectively. Ranges of parameters were through-flow Reynolds number, 1,000–15,000; rotation number, 0–0.32; rotationalbuoyancy parameter, 0–1.2; and cross-sectional aspect ratio, 0.5, 1.0, and 2.0. The results showed that the higher the rotationnumber, the greater the enhancement ofthe heat transfer rate especially at the pressure side. The rotational buoyancy parameterdecreases the heat transfer for low Re but enhances the heat transfer for high Re. The largest heat transfer enhancement isseen for AR = 1.0, and the enhancement for AR = 0.5 is greater than that for AR = 2.0
