Investigation of Performance and Rotor Tip Flow Field in a Low Speed Research Compressor with Circumferential Groove Casing Treatment at Varying Tip Clearance
Figure 6
Standard deviation of casing static pressure over rotor for SolidWall and Groove at = 1.2% and = 2.5% at three different operating points ((a, d, g, j): design point, (b, e, h, k): throttled operating point, and (c, f, i, l): near stall of current configuration).
