The influence of inlet flow distortion on the performance of a centrifugal compressor and the development of improved inlet using numerical simulations

摘要

The performance of centrifugal compresosrs can be seriously affected by the inlet flow distortion that is by non-uniform inlet flow. The distortion can be in static pressure or stagnation temperature, but the most common distortion is stagnation pressure. Such distortions often occur because of the unsatisfactory nature of the inlet configuration and the resulting inlet flow structure.
