Abstract
An apparatus achieves passive damping of flow disturbances to control centrifugal compressor surge. The apparatus includes be a centrifugal compressor for compressing a low pressure fluid, the centrifugal compressor has an impeller, an inlet which communicates with an atmosphere, and a discharge through which compressed air is supplied to a compressed air system. A vane diffuser assembly fluidly communicates with the impeller. The diffuser assembly has at least one vane connected to passive elements so as to damp low amplitude flow disturbances of the compressible fluid. The diffuser assembly forms an annular-shaped plenum which communicates with high static pressure fluid. The apparatus also includes a diaphragm integrally mounted within the annular-shaped plenum. The diaphragm is for damping low amplitude flow disturbances of the compressible fluid.
