| Abstract: | Heat transfer in the tail section of channel of cooling blade with pin-fin arrays is studied. According to the theoretical calculation, a curvilinear pin-fin shape is acquired which make the maximum heat transferred under certain conditions. The quantity of heat transferred is compared with that of corresponding cylindrical pin-fin arrays to show the advantage. Finally, the relations of the heat transfer to the rib's physical parameters or geometrical characters are analyzed systematically. |

| Keywords: | pin-fin enhanced heat transfer curvilinear shape |
