An airfoil component for use in a turbomachine, and method of promoting the heat transfer characteristics within the component. The component includes an airfoil portion having a span-wise direction delimited by an airfoil root and airfoil tip, and a chord-wise direction delimited by leading and trailing edges. A chamber within the airfoil portion contains a permeable foam member. The chamber is fluidically connected to a cooling fluid source and to a cooling hole through first and second passages, respectively, within the airfoil portion. The chamber is located relative to the first and second passages so as to be offset in the chord-wise direction therefrom so that cooling fluid entering the chamber through the first passage is diverted by the foam member in the chord-wise direction before exiting the airfoil portion through the cooling hole. |
