Blade assembly for turbomachine

摘要

The surface of the blade (1) or a wall (2) in the region of corner flow is provided with at least one auxiliary blade extending from the surface of the blade and/or wall into the flow, set against the flow at this point. In the wake of the auxiliary blade, an eddy is formed whose rotation direction is directed to induce a velocity on the associated blade surface from the blade center to the transition region between wall and blade.
