Using vortex generators to delay diffuser separation can lead to significant consequences if they stall, particularly in terms of flow distortion that negatively impacts pressure recovery. Setting the generators at an angle of attack beyond the stall point can exacerbate this issue, resulting in reduced efficiency. Research indicates that understanding the stall behavior of vortex generators is critical for optimizing their performance in turbomachinery applications. Relevant studies can be found in reputable journals such as ASME's Journal of Turbomachinery and AIAA's publications. Properly addressing these factors is essential for effective design and operation.
