Abstract
A compressor arrangement has a main compressor section and boundary walls of a main fluid path through the main compressor section. The main compressor section is segmented into an upstream and downstream sub section, each with at least one row of blades and vanes arranged within the main fluid path. A transition piece is downstream of the rows of blades and has boundary walls of the main fluid path through the transition piece. The compressor arrangement has an annular cavity, an effusion opening connecting the downstream sub section or the transition piece and the cavity, at least one valve to control effusion of compressor fluid from the main fluid path into the cavity, and a passage connecting the cavity and the main compressor section to guide fluid located between the upstream and downstream sub section and located at least one row of blades and vanes upstream of the effusion opening.
