摘要:
An axial flow fluid apparatus axially provided with a plurality of blade rows having a plurality of blades arranged around a shaft is provided. A fluid passage for jetting a fluid to a downstream velocity defect region resulting from a blade is formed in at least one of blades constituting a blade row installed on the upstream side of the plurality of blade rows so as to lead from a positive pressure surface to a negative pressure surface or a trailing edge.
