... of 2EO generated inside the blade passage cannot be ignored. Moreover, the relative velocities at the LE are also calculated when the blade enters the distorted region under other circumferential distortion extents. The values in the 150-deg, 120-deg, 90-deg, and 60-deg cases are 299.16 m/s, 302.57 m/s...
