In contrast, the Mach number distri- bution shows a common minimum for clocking angles corresponding to the first stator wake.
Consequently, the truncated wake of the first stator interacts mainly with this pressure field for clocking angles 0, 1, and 2, where higher circumfer- ential gradients of the Mach number prevail.
More homogeneous Mach numbers are observed at 5 and 6 clocking angles, where first stator wake segments reach the midregion of the second stator vane passage.
Figure 8.26 shows a comparison of the total relative efficiency for various clocking angles, indicating a clear advantage for the 0 position.
