Erratum: “Secondary Flows, Endwall Effects, and Stall Detection in Axial Compressor Design” (ASME J. Turbomach. (2015) 137:5 (051004) DOI: 10.1115/1.4028648)
Abstract
In the published paper, the expressions listed under (51) were miswritten. The correct version is – for a rotor: (w2/w1)T < Ctc(WR min)T /1.3 (w2/w1)A < (WR min)A (w2/w1)H < (WR min)H /1.3 –for a stator: (w2/w1)T < (WRmin)T/1.3 (w2/w1)A < (WRmin)A (w2/w1)H < Ctc(WRmin)H/1.3 (51) And the following sentence should be: “Hub and tip minimum velocity ratios are divided by a factor of 1.3 due to the ability of the blade row to operate stably in spite of the presence of corner stall.” In Eq. (56), member (WRmin)M is wrongly labeled, and it should be replaced with (WRmin)A. The correct version of the equation is Ctc = 1 /(WR, min)A √1 − Ktc(1 − (WR, min)2/A)–for a stator: (w2/w1)T < (WRmin)T/1.3 (w2/w1)A < (WRmin)A (w2/w1)H < Ctc(WRmin)H/1.3 (51) And the following sentence should be: “Hub and tip minimum velocity ratios are divided by a factor of 1.3 due to the ability of the blade row to operate stably in spite of the presence of corner stall.” In Eq. (56), member (...WRmin)M is wrongly labeled, and it should be replaced with (WRmin)A. The correct version of the equation is Ctc = 1 /(WR, min)A √1 − Ktc(1 − (WR, min)2/A).
