Steampath flow separation reduction system

摘要

A system for reducing flow separation in a turbo machine is provided, the system including a stationary vane (22) coupled to a stationary vane support (32); at least one circumferential extraction band (107) through the stationary vane or the stationary vane support (32); the circumferential extraction band (107) having a first side proximate to an operative fluid flow (128) through the turbo machine; at least one opening in the first side of the circumferential extraction band (107); and a channel (110) having a first end in fluid connection with the circumferential extraction band (107) and a second end extending through the stationary vane support (32), such that the operative fluid (128) flow through the turbo machine is redirected through the extraction opening (108) into the circumferential extraction band (107) and through the channel (110) towards a rotating blade (20).
