Oscillatory Tip Leakage Flows and Stability Enhancement in Axial Compressors

Figure 2

The top two pictures show the relative Mach number contours at 99% span, a plane at the middle of the tip clearance, at points PE and NS. The bottom two pictures depict the blade loadings using the surface pressure coefficient distributions along the blade’s axial chord. ([12]). Figure reproduced from LIN et al. (2010).
