Abstract EN
The turbine blade works at high thermal loads, especially the trailing edge of the blade due to the hot gas leakage flow.
Pin-fins are well recognized as a kind of effective device to augment the convective heat transfer and effectively cool the trailing edge.
In this paper, the cooling effectiveness of chordwise outlet pin-fins distance and inner pin fin diameter is, respectively, studied on the heat transfer and flow friction of the trailing edge of the blade with software CFX.
A 90 deg turn cooling wedge passage with cylindrical pin-fins is used to model the trailing edge.
Results show that the pin-fins distance at the outlet and the arithmetic arrangement of the inner pin-fins diameter both are vital factors to influence the cooling effectiveness in the trailing edge of the blade.
