High blowing ratio high effectiveness film cooling configurations
Abstract
A film cooled component is provided that includes a body having a cavity defined therein, wherein a coolant is supplied to the cavity cooling apertures having at least one channel defined on an inside surface. The coolant exits the cavity through the plurality of cooling apertures thereby providing a cooling effect to the body and the channel creates an air flow such that the air coolant moves towards the body upon exiting the plurality of cooling apertures. The film cooled component may include cooling apertures configured to reverse blow coolant air.
