PASSIVE NOISE ATTENUATION SYSTEM |
摘要 |
A passive noise attenuation device and system is provided having a reticulated open-cell porous structure configured to acts as a passive control device in order to mitigate combustion noise and instability problems in combustion systems. A porous inert media structure is placed downstream of the reaction zone of a combustion chamber to dissipate noise and/or instability generated upstream in the flame. The porous inert media also limits and/or disintegrates vortical structures in the flame to produce a homogeneous flow field to facilitate distributed reaction zones.
