Wider upstream wakes increase mixing losses within the cascade, resulting in a significant rise in entropy loss coefficients.
The study compares the effects of two distinct wake widths on leakage flows in a multistage compressor setting.
Unsteady numerical simulations were employed to decouple interactions between wake influences and cantilever cascade flows.
The findings suggest that optimizing wake conditions can stabilize airflow and improve overall compressor performance.
