GAS TURBINE INLET SILENCER |
摘要 |
<p>A system for attenuating sound emissions from an inlet to a flow path for an air inducting machine including an inlet duct structure having inlet and outlet passages. A planar vortex generator is located adjacent to the outlet passage and creates vortices that interact with a specific tonal acoustic frequency emitted from the inlet of the machine to effect formation of a standing wave at the vortex generator. The standing wave has an upstream propagating component that reflects off an acoustic reflector wall to form a reflected component that interferes with the upstream propagating component to attenuate the specific tonal acoustic frequency from the inlet of the machine.</p> |
