description abstract | The heat transfer characteristics of a rotating pin-fin roughened wedge-shaped channel have been studied. The model incorporates ejection through slots machined on the narrower end of the wedge, simulating a rotor blade trailing edge. The copper plate regional average method is used to determine the heat transfer coefficient; pressure taps have been used to estimate the flow discharged through each slot. Tests have been conducted at high rotation (≈1) and buoyancy (≈2) numbers, in a pressurized rotating rig. Reynolds numbers investigated range from 10,000 to 40,000 and inlet rotation numbers range from 0 to 0.8. Pin-fins studied are made of copper. Results show high heat transfer in the proximity of the slot. A significant enhancement in heat transfer due to the pin-fins, compared with a smooth channel, is observed. Results also show a strong rotation effect, increasing significantly the heat transfer on the trailing surface and reducing the heat transfer on the leading surface. | |
