Acoustic resonator device for combustion chamber, has front-sided opening connecting resonator and combustion areas, and fluid permeable resonance influencing elements producing turbulence and arranged in resonator area

摘要

The device (22) has a combustion area (14) including a wall and forming a resonator area (28). A front-sided opening (29) connects the areas. Resonance influencing elements are arranged in the area (28). The elements are fluid permeable and produce turbulence. Grids and porous structures are arranged as the elements. The elements are arranged at or in proximity of the opening (29). The elements extend over the entire cross section of the area (28). The elements are made of metallic or ceramic material. The porous structures are made of a synthetic material. An independent claim is also included for a combustion chamber device.
