Abstract
This experimental study measured the detailed Nusselt numbers (Nu) distributions over two opposite leading and trailing walls of a rotating parallelogram square two–pass channel enhanced by transverse ribs using infrared thermography. The effects of Reynolds (Re), rotation (Ro) and buoyancy (Bu) numbers on local and area-averaged Nusselt numbers (Nu and ) over the rotating leading and trailing ribbed endwalls were examined at the test conditions of Re=5,000~20,000, Ro=0~0.15 and Bu=0.002~0.029 as the first attempt to reveal the combined rotating buoyancy and Coriolis force effects on the detailed heat transfer properties of the rotating parallelogram two-pass channel with transverse ribs.
