Abstract
Official abstract text for this publication.
A resonance chamber ( 42 ) has an outer wall ( 32 ) with coolant inlet holes ( 34 A-C), an inner wall ( 36 ) with acoustic holes ( 38 ), and side walls ( 40 A-C) between the inner and outer walls. A depression ( 33 A-C) in the outer wall has a bottom portion ( 50 ) that is close to the inner wall compared to peaks ( 37 A-C) of the outer wall. The coolant inlet holes may be positioned along the bottom portion of the depression and along a bottom portion of the side walls to direct coolant flows ( 44, 51 ) toward impingement locations ( 43 ) on the inner wall that are out of alignment with the acoustic holes. This improves impingement cooling efficiency. The peaks ( 37 A-C) of the outer wall provide volume in the resonance chamber for a target resonance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A damping resonator comprising: a resonance chamber formed by an outer wall with coolant inlet holes, an inner wall with acoustic holes, and side walls spanning between the inner and outer walls; a depression in the outer wall comprising a bottom portion that is closer to the inner wall than is a first peak portion of the outer wall; the coolant inlet holes distributed along the bottom portion of the depression; wherein the coolant inlet holes ar…
