Abstract
Ported Shroud for a turbocharger allows air from downstream of compressor to recirculate back to upstream to increase flow stability and avoid surge. To expand the operating range of a centrifugal compressor, shroud walls often have annular ribs. This invention proposes a reversed design of ported shroud rib that improves compressor surge behavior and widens compressor map without any additional cost.
