Performance of a cascade in an annular vortex-generating tunnel over range of Reynolds numbers

Thurston, Sidney., Brunk, Ralph E.

Total-pressure deficiency for an annular cascade of 65-(12)10 blades was measured at three radial stations over a range of Reynolds numbers from 50,000 to 250,000 and at angles of attack of 15 degrees and 25 degrees. The variation of turning angle and shape of static pressure distribution at these stations is also shown.
