<P>PROBLEM TO BE SOLVED: To greatly enhance heat transfer efficiency of an airfoil component. <P>SOLUTION: An airfoil component for use in a turbomachine and a method for enhancing heat transfer characteristics within the component. The component includes a span-wise direction delimited by an airfoil root (22) and airfoil tip (20), and a chord-wise direction delimited by a leading edge (16) and a trailing edge (18). A chamber (28) in an airfoil portion (10) contains a permeable foam member (30). The chamber (28) is fluidically connected to a cooling fluid source and a cooling hole (26A) through first passage (24A) and second passage (24B), respectively, in the airfoil portion (10). The chamber (28) is located relative to the first and second passages (24A, 24B) so as to be offset in the chord-wise direction therefrom so that cooling fluid entering the airfoil portion (10) enters the chamber (28) through the first passage (24A), and is diverted by the foam member (30) in the chord-wise direction before exiting the airfoil portion (10) through the first cooling hole (26A). <P>COPYRIGHT: (C)2012,JPO&INPIT |
