Abstract
Methods and systems are provided for mitigating noise generated by a compressor operating at low flow rates. A swirl device with two concentric flow passages upstream of the compressor directs intake air flow to the compressor through two different flow paths, depending on air flow rates. Angled swirl vanes at an outlet of the swirl device pre-whirl the air flowing to the compressor to reduce noise generation at low air flow rates.
