Definitions

the rear boundary point of the annular channel wall recess F is at a distance f behind the leading edge point A, where 0.5 L> f> 0.
Fig.7a to 7c each show in the view ZZ a settlement of the circumference of the fluid flow machine in the region of the Ringkanalwandausappelung. Dotted indicate two blades of the relevant row of blades, on which the recess is arranged. Shown are, in partial overlap with the blade row, the openings of an array of recesses on the annular channel wall. According to the invention, the openings in the flow direction of slender nature, ie, the extent in the circumferential direction is smaller than the extent perpendicular thereto.
