ABSTRACT:
In a turbo compressor, such as a centrifugal compressor, having swirl inducing structure, such as inlet guide vanes, one or more free rotors are located intermediate the swirl inducing structure and the inlet of the compressor. The free rotors are driven by the flow and the kinetic energy stored therein serves to mitigate transient changes in the flow as perceived at the inlet of the compressor such that a more stable operation results.
