Airfoil insert and method for cooling an airfoil |
摘要 |
<p>An airfoil insert (10) comprises an insert wall (11), a contact element (14) and a flow director. The insert wall defines an interior (15) extending inside the insert wall from a first end (12) to second end (13), and an exterior (16) extending outside the insert wall from the first end to the second end. The contact element (14) is formed on the exterior of the insert wall (11). The flow director is formed on the insert wall (11) at a boundary between the interior and the exterior. The flow director increases a heat transfer coefficient of convective flow along the insert wall by directing the convective flow to the exterior of the insert wall. A method for cooling an airfoil (20) is also disclosed.</p> |
